Abstract

Disclosed is a vibration source attachment structure equipped with a vibration isolation device. In the vibration source attachment structure, the vibration source (41) of an engine, or the like, is attached via the vibration isolation device (50) to a subframe (30) that has been attached in a downward position with respect to a vehicle body frame (20). The vibration isolation device (50) is provided with a first attachment (51) that attaches to the vibration source (41), a second attachment (52) that attaches to the subframe (30), and an elastic body (53) that connects the first and second attachments (51, 52). The subframe (30) is provided with fitting holes (31) that are formed in the vertical direction of said subframe. The second attachment (52) is detachably attached to the fitting holes (31) by means of press fitting.

Claims

1. A vibration source attachment structure comprising a vehicle body frame, a subframe disposed below the vehicle body frame and attached to the vehicle body frame, and an engine or other vibration source attached to the subframe via a vibration isolation device, characterized in that:

the vibration isolation device has a first attachment part attached to the vibration source, a second attachment part attached to the subframe, and an elastic body connecting the first attachment party and the second attachment part;

the subframe has a fitting hole formed in a vertical direction of the subframe; and

the second attachment part is attached to the fitting hole by detachable press-fitting.

2. The vibration source attachment structure according to claim 1, wherein the second attachment part has a positioning stopper for positioning the press-fitting direction relative to the subframe during press-fitting into the fitting hole.

3. The vibration source attachment structure according to claim 1, wherein the subframe has a detachable retaining stopper for preventing the second attachment part press-fitted into the fitting hole from falling off in a direction opposite to the press-fitting direction.
