Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
In a motor vehicle having an engine and a transmission gear box supported through cushion means on a beam secured to the body of said vehicle, and an exhaust system having a catalytic converter operatively connected to an exhaust manifold of said engine through an exhaust pipe, the improvement comprising: a basic member interposed between said transmission gear box and said cushion means and secured to said transmission gear box so that said basic member is vibrated substantially integrally with said engine; a cushion member; and an exhaust pipe holding member having one end connected to said basic member through said cushion member, and the other end securing said exhaust pipe.
Claim 2
Dependent Claim
111 words
In a motor vehicle having an engine and a transmission gear box supported through cushion means on a beam secured to the body of said vehicle, and an exhaust system having a catalytic converter operatively connected to an exhaust manifold of said engine through an exhaust pipe, the improvement comprising: a basic member interposed between said transmission gear box and said cushion means and secured to said transmission gear box so that said basic member is vibrated substantially integrally with said engine; a cushion member; and an exhaust pipe holding member having one end connected to said basic member through said cushion member, and the other end securing said exhaust pipe.
Claim 3
Dependent Claim
42 words
The improvement as claimed in claim 1, in which said exhaust pipe holding member includes: a bracket secured at its one end to said cushion member; and an annular member connected to said bracket to fasten said exhaust pipe to said bracket.

The improvement as claimed in claim 1, in which said basic member has an inverted U-shaped cross section and is mounted on said beam through said cushion means and said cushion member is made of a rubber, and in which said exhausted pipe holding member includes a bracket secured at its one end to said basic member through said cushion member, and a ring shaped fixing member secured to the other end of said bracket for fastening said exhaust pipe.
Claim 7
Dependent Claim
173 words
In a motor vehicle having an engine and a transmission gear box supported through cushion means on a beam secured to the body of said vehicle, and an exhaust system having a catalytic converter operatively connected to an exhaust manifold of said engine through an exhaust pipe, the improvement comprising: a basic member having a generally U-shaped cross section mounted on said cushion means, said basic member being interposed between said transmission gear box and said beam, and secured to said transmission gear box so that said basic member is vibrated substantially integrally with said engine; a cushion member including a ring-shaped metal spring having an upper end connected to said basic member through a first bracket; and an exhaust pipe holding member including a second bracket secured at its one end to a lower end of said ring-shaped metal spring, and an U-shaped fastening member connected to the other end of said second bracket in order to fasten a portion of said exhaust pipe adjacent said catalytic converter to said second bracket.
Claim 8
Dependent Claim
173 words
