BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power unit mounting structure.

[0002]

2. Description of the Related Art Conventional mount structures of this type include:
There is a technique disclosed in Japanese Utility Model Laid-Open No. 56-69521. This disclosed technique uses inner and outer members 2 fixed to each other via a mount rubber 20 as shown in FIGS.
Flange portions 23, 24, 25, at both ends of the first and the second so as to be substantially parallel to each other and spaced from each other.
26, stoppers 25a, 26a are provided inside the flange portions 25, 26 of the outer member 22, a protrusion 27 is formed in the flange 23 of the inner member 21, and a through hole 28 is formed in the protrusion 27. The flange portion 25 of the outer member 22 is penetrated through the through hole 28, and the end portion of the flange portion 25 is bent upward to use the bent end portion as the stopper 25b.

The stoppers 25a and 26a are moved by the flanges 2 of the inner member 21 against the front-rear movement of the mounted member (not shown) held by the mounting structure.
3 and 24, the movement of the mounted member in the front-rear direction is regulated, and at the time of rebound, the stopper 25b of the flange 25 of the outer member 22 is brought into contact with the protrusion 27 of the inner member 21 to mount the mounted member. The vertical movement of the member is restricted.

[0004]

However, in the above-mentioned conventional mounting structure, a member for restricting the movement of the mounted member in the front-rear direction is attached to the flange portions 25 and 26 of the outer member 22 by the inner member. 21 with stoppers 25a and 26a facing the flanges 23 and 24,
Further, a through-hole 28 is formed in a protruding portion 27 formed in the flange portion 23 of the inner member 21 for regulating the movement of the mounted member in the vertical direction.
2 through the flange 25, the end of the flange 25 is bent upward, and the bent end is
In addition, since the stopper 25b is configured to abut on the protruding portion 27 of the inner member 21, there is a problem that the configuration is complicated and the cost is increased.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a mount structure which has a simple structure and is inexpensive.

[0006]

In order to achieve the above object, the present invention provides an outer member attached to a mounted member, an inner member attached to a holding side member inside the outer member, and an inner member attached to the holding member. , An elastic member interposed between the outer members, a space is provided above the elastic member, between the outer member, and a front and rear of a mounting surface of the outer member.
Previous outer member side and bent at right angles, the rear bent portion is formed and an end of the end portion of the bent portion of the front bent rearwardly to form a stopper portion of the front, the rear bent portion Fold the part forward to form the rear stopper,
Before the inner material side before and after attachment surface portion of said member and bent at right angles, to form the rear side bent portion, before the inner member side, respectively outward the central portion of the rear bent portion A bulging portion bulging toward the front is formed as a stopper pressure receiving portion, and a vertical movement margin of the front and rear stopper portions with respect to the stopper pressure receiving portion is secured, and the front and rear stopper portions and the holding portion are held. The front and rear vertical wall portions of the side members are configured to regulate the front-rear direction while securing a movement allowance.

[0007]

By the action Such configuration, the front in the front-rear direction of the front to move the rear of the stopper portion said retaining member of the mounting member, it hits the vertical wall portion of the rear movement of the front-rear direction of the mounting member There line regulations, also, at the time of rebound,
The front and rear stopper portions contact the stopper pressure receiving portion, and regulate the vertical movement of the mounted member.

[0008]
