## Abstract

A vibration isolating mount 17 accommodates an elastic member 20 in the interior of a housing 18 fixed to a vehicle body 16 and a bracket 22 one end of which is fixed to the driving source 11. The other end of the bracket 22 is engaged in a bracket connecting part 21 provided in the elastic member 20. A space β in the longitudinal direction between a rear wall 21d of the bracket connecting part 21 and a rear stopper surface 18e of the housing 18 is set to be smaller than a space α in the longitudinal direction between the front wall 21c of the bracket connecting part 21 and a front stopper surface 18d of the housing 18, so that the rearward displacement of the driving source 11 may be effectively suppressed.

## Claims

### Claim 1

A support structure for a driving source comprising:
a bracket one end of which is fixed to a driving source; and
a vibration isolating mount comprising:
a housing fixed to a vehicle body and having an interior space which has a rear stopper surface and a front stopper surface; and
an elastic member housed in the interior space of the housing and having a bracket connecting part to which another end of the bracket is connected, the bracket connecting part having a rear wall which faces the rear stopper surface of the housing and a front wall which faces the front stopper surface of the housing,
wherein a gap formed in the front-to-rear direction between the rear wall of the bracket connecting part and the rear stopper surface of the housing is set to be smaller than a gap formed in the front-to-rear direction between the front wall of the bracket connecting part and the front stopper surface of the housing.

### Claim 2 (depends on 1)

The support structure for the driving source according to claim 1, wherein a thickness in the front-to-rear direction of the rear wall is larger than a thickness in the front-to-rear direction of the front wall.

### Claim 3 (depends on 2)

The support structure for the driving source according to claim 2, wherein a cross sectional area of the rear wall of the bracket connecting part is tapered rearward.

### Claim 4 (depends on 1)

The support structure for the driving source according to claim 1, further comprising a mass body mounted on an upper surface of the housing,
wherein a front part and a rear part of the mass body are fastened to the housing by a fastening member.

### Claim 5 (depends on 4)

The support structure for the driving source according to claim 4,
wherein the mass body is provided with a front fastening hole and a rear fastening hole through each of which the fastening member passes, and
wherein the mass body has a first recess formed between the front fastening hole and the rear fastening hole such that the mass body has an accessible space opened in a vehicle width direction and a second recess formed by cutting out a circumference of the rear fastening hole in a circular arc shape.
