Abstract

Abstract Disclosed herein in a mount structure where a shift lever retainer for spherically supporting a shift lever is mounted through a vibration damping member to a transmission case by a bolt, a vibration damping structure comprising a stopper means for preventing horizontal and vertical deformations of the vibration damping member greater than a predetermined amount. With this arrangement, there is no possibility that rigid feeling in operating of the shift lever is decreased, that is, shift feeling is deteriorated. Further, vibration of the shift lever and associated noise may be greatly reduced.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 222 words
In a shift lever retainer mounting structure including a shift lever retainer for spherically supporting a shift lever, a first vibration damping member interposed between said shift lever retainer and a transmission case, a bolt for fixing said shift lever retainer to said transmission case, a second vibration damping member interposed between said bolt and said shift lever retainer, and a bushing for receiving said bolt, said bushing having an upper flange arranged between a head portion of said bolt and said second vibration damping member, said first and second vibration damping members having a thickness such that vibration from said transmission case may be sufficiently absorbed; a vibration damping structure comprising a first stopper means for preventing horizontal deformation of said first vibration damping member greater than a predetermined amount, and a second stopper means for preventing vertical deformation of said first vibration damping member greater than a predetermined amount, wherein said first stopper means comprises a rigid ringlike member engaged with said bushing and located between said first and second vibration damping members, and wherein said second stopper means comprises an upward projection projecting from a plate engaged with said bolt and fixed on an upper surface of said transmission case such that a portion of said plate is interposed between said first vibration damping member and said transmission case.
Claim 2
Dependent Claim 222 words
In a shift lever retainer mounting structure including a shift lever retainer for spherically supporting a shift lever, a first vibration damping member interposed between said shift lever retainer and a transmission case, a bolt for fixing said shift lever retainer to said transmission case, a second vibration damping member interposed between said bolt and said shift lever retainer, and a bushing for receiving said bolt, said bushing having an upper flange arranged between a head portion of said bolt and said second vibration damping member, said first and second vibration damping members having a thickness such that vibration from said transmission case may be sufficiently absorbed; a vibration damping structure comprising a first stopper means for preventing horizontal deformation of said first vibration damping member greater than a predetermined amount, and a second stopper means for preventing vertical deformation of said first vibration damping member greater than a predetermined amount, wherein said first stopper means comprises a rigid ringlike member engaged with said bushing and located between said first and second vibration damping members, and wherein said second stopper means comprises an upward projection projecting from a plate engaged with said bolt and fixed on an upper surface of said transmission case such that a portion of said plate is interposed between said first vibration damping member and said transmission case.
Claim 3
Dependent Claim 19 words
The vibration damping structure as defined in claim 2, wherein said plate is formed in a substantially fan-like shape.
