Abstract
Abstract A shift lever is composed of a lower lever section connected to a control rod of a transmission, and an upper lever section formed with a hollow cylindrical portion and provided with a shift lever knob. The lower lever section is formed with an elongate end portion which is being inserted in the hollow cylindrical portion of the upper lever section. Additionally, lower and upper elastomeric insulators spaced from each other are securely mounted on the elongate end portion of the lower lever section. The lower elastomeric insulator is securely connected to the upper lever section cylindrical portion, while the upper elastomeric insulator is adapted to form a clearance between it and the upper lever section cylindrical portion, thereby avoiding contact between the upper elastomeric insulator and the upper lever section cylindrical portion upon the shift lever being not operated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
A shift lever comprising: a first lever section having an elongate end portion which is substantially rigid; a second lever section having an elongate hollow cylindrical portion in which said first lever section end portion is disposed; first and second elastomeric insulators securely mounted on said first lever section end portion and spaced apart from each other in an axial direction of said first lever end portion; means for securely connecting said first elastomeric insulator with said second lever section cylindrical portion; and means forming a clearance between said second elastomeric insulator and said second lever section cylindrical portion.
Claim 2
Dependent Claim
99 words
A shift lever comprising: a first lever section having an elongate end portion which is substantially rigid; a second lever section having an elongate hollow cylindrical portion in which said first lever section end portion is disposed; first and second elastomeric insulators securely mounted on said first lever section end portion and spaced apart from each other in an axial direction of said first lever end portion; means for securely connecting said first elastomeric insulator with said second lever section cylindrical portion; and means forming a clearance between said second elastomeric insulator and said second lever section cylindrical portion.
Claim 3
Dependent Claim
35 words
A shift lever as claimed in claim 1, wherein said clearance forming means includes means for establishing contact between said second elastomeric insulator and said second lever cylindrical portion upon said shift lever being operated.
Claim 4
Dependent Claim
43 words
A shift lever as claimed in claim 1, wherein said first lever section is connected to a control rod of a transmission, wherein said second lever section is provided at an end portion opposite to said cylindrical portion with a shift lever knob.
Claim 5
Dependent Claim
33 words
A shift lever as claimed in claim 3, wherein said first lever section is provided with a sperhical ball fulcrum through which said first lever section is pivotally supported on a stationary member.
Claim 6
Dependent Claim
26 words
A shift lever as claimed in claim 3, wherein said second elastomeric insulator is located nearer to said shift lever knob than said first elastomeric insulator.
Claim 7
Dependent Claim
43 words
A shift lever as claimed in claim 5, wherein said first lever section end portion is a straight elongate rod, wherein said second lever section cylindrical portion is so disposed as to be locatable generally coaxial with said first lever section elongate rod.
Claim 8
Dependent Claim
20 words
A shift lever as claimed in claim 6, wherein said first elastomeric insulator is cylindrical and has an annular cross-section.
Claim 9
Dependent Claim
63 words
A shift lever as claimed in claim 6, wherein said second elastomeric insulator is cylindrical and has an annular cross-section, said cylindrical second insulator being disposed coaxial with said first lever section elongate rod so that a cylindrical clearance is formable between an outer peripheral surface of said second elastomeric insulator and an inner peripheral surface of said second lever section cylindrical portion.
Claim 10
Dependent Claim
45 words
A shift lever as claimed in claim 6, wherein said first and second elastomeric insulators are integrally connected with each other through an elastomeric insulator connecting section whose outer peripheral surface is spaced from an inner peripheral surface of said second lever section cylindrical portion.
Claim 11
Dependent Claim
121 words
A shift lever comprising: a first lever section having an elongate end portion; a second lever section having an elongate hollow cylindrical portion in which said first lever section end portion is disposed; first and second elastomeric insulators securely mounted on said first lever section end portion and spaced apart from each other in axial direction of said first lever end portion; means for securely connecting said first elastomeric insulator with said second lever section cylindrical portion; means forming a clearance between said second elastomeric insulator and said second lever section cylindrical portion; and a collar disposed between said first elastomeric insulator and said second lever section cylindrical portion in a manner to provide a preload on said first elastomeric insulator.
Claim 12
Dependent Claim
121 words
A shift lever comprising: a first lever section having an elongate end portion; a second lever section having an elongate hollow cylindrical portion in which said first lever section end portion is disposed; first and second elastomeric insulators securely mounted on said first lever section end portion and spaced apart from each other in axial direction of said first lever end portion; means for securely connecting said first elastomeric insulator with said second lever section cylindrical portion; means forming a clearance between said second elastomeric insulator and said second lever section cylindrical portion; and a collar disposed between said first elastomeric insulator and said second lever section cylindrical portion in a manner to provide a preload on said first elastomeric insulator.
