Abstract

A power unit mounting structure of a vehicle includes a power unit 100, a sub frame 200 disposed below the power unit 100 in the vehicle height direction and at least one attaching bracket 220 for attaching the power unit 100 on the sub frame 200, the power unit 100 has an arm 210 extended from the main body portion thereof to the attaching bracket 220, a tip portion of the arm 210 is axially supported on a pair of shaft supporting portions 221 of the attaching bracket 220 with a shaft member 213 extended to the width direction of the vehicle, and the shaft supporting portion 221 of the attaching bracket 220 has fragile portions 222, 223 which break when the impact is applied such that the aria 210 of the power unit 100 shifts to the front direction.

First claim

The invention claimed is:

1. A power unit mounting structure of a vehicle, comprising:
a power unit having an main body and an extending arm which extends from the main body and has a front portion to be supported by a vehicle body;
a sub frame of the vehicle body disposed below said power unit in a vehicle height direction; and
at least one attaching bracket provided to said sub frame and attached to the front portion of the extending arm of said power unit, thereby supporting said power unit, wherein
the at least one attaching bracket is provided with a shaft member and a pair of shaft supporting portions which support axial ends of the shaft member in a vehicle width direction, the shaft member axially supporting the front portion of said extending arm, and
the pair of shaft supporting portions of said attaching bracket have fragile portions configured to break or deform, when an impact is applied thereto, so as to allow the extending arm of said power unit to move toward a front side of the vehicle.

2. The power unit mounting structure according to claim 1 , wherein said fragile portions comprise at least one of a slit and a groove portion.

3. The power unit mounting structure according to claim 1 , wherein said sub frame has a bent portion.

4. The power unit mounting structure according to claim 1 , wherein said extending arm has a rigidity higher than a rigidity of the shaft supporting portions of said attaching bracket.

5. The power unit mounting structure according to claim 1 , wherein
the front portion of said extending arm has an axially opened hole,
an elastic body is coaxially fitted into said axially opened hole,
a metal member is coaxially fitted into the elastic body and has an insertion hole into which said shaft member is inserted, such that said elastic body holds said metal member in a vehicle front-rear direction.
