Then, as the pushing piece C2 is engaged with the engaging piece B2 of the rubber member B with the insertion into the rubber member B, the engaging piece B2 of the rubber member B is pushed by the pushing piece C2 of the bush C. When the flange piece C3 of the bush C is pushed out and comes to a position where the flange piece C3 of the bush C comes into contact with the flange piece B3 of the rubber member B, the engagement piece B2 is engaged with the locking edge 6a of the mounting hole 6.
Engage from inside. At the same time, Bush C
The pushing piece C2 of FIG. 3 engages with the upper edge of the opening B4 formed in the cylindrical portion B1 due to the outward bending of the engaging piece B2 (see FIG. 3).

As a result, the rubber member B is prevented from falling out of the mounting hole 6, and the bush C is also prevented from falling out of the rubber member B. With this, the operation of assembling the rubber member B is completed, and the rubber member B and the bush C are integrally assembled to the connector housing 3. Then, in this state, the connector A is shipped from a factory or the like.

When the rubber member B and the bush C are assembled, the lower end of the rubber member B and the lower end of the bush C slightly project from the back surface of the fixed plate 1. In order to attach the connector A with the rubber member B attached thereto to the engine 8 or the like, the lower end of the bush C protruding from the back surface of the fixing plate 1 is pressed against the engine 8 or the like, Then, the bolt 7 may be inserted from above and tightened to the side of the engine 8 or the like. At the time of this tightening, the bush C is
Since the connector plate 3 is stretched between the connector housing 3 and the like, the fixing plate 1 is prevented from being excessively tightened.

When the connector A is attached to the engine 8 or the like, the fixing plate 1 is held in a state of slightly rising from the engine 8 or the like, and a rubber is provided between the fixing plate 1 and the head of the bolt 7. Since the flange B3 of the member B is interposed, the vibration of the engine 8 and the like is not directly transmitted to the connector A, but the vibration transmitted to the bolt 7 is transmitted to the connector A via the rubber member B. Therefore, the vibration of the engine 8 and the like is prevented from being absorbed by the rubber member B and transmitted to the connector A.

As described above, in this embodiment, the rubber member B
Can be assembled in the connector housing 3 in advance, so that it is not necessary to assemble the rubber member B when the connector A is attached to the engine 8 or the like, thereby eliminating troublesome work and improving workability. In addition, since the product can be shipped with the rubber member B attached to the connector housing 3, the rubber member B
It is no longer necessary to manage as a single unit, and the burden on parts management is reduced. Furthermore, since the rubber member B is assembled to the mounting hole 6 using the bush C for preventing excessive tightening, it is not necessary to provide a dedicated member for assembling the rubber member B.

The present invention is not limited to the above-described embodiment, but can be modified and implemented as follows, for example, and these embodiments also belong to the technical scope of the present invention. (1) In the above embodiment, the rubber member B is engaged with the mounting hole 6 using the bush C. However, the configuration may be such that the bush is not used. For example, as shown in FIG. 4, an engagement protrusion D <b> 2 is formed on the outer peripheral surface of the cylindrical portion D <b> 1 of the rubber member D, and this is engaged with the locking edge 6 a of the mounting hole 6. As shown in FIG. 5, an engagement hole E2 is formed on the outer peripheral surface of the cylindrical portion E1 of the rubber member E, and the engagement edge 6a of the attachment hole 6 is engaged with the engagement hole E2. Furthermore, a configuration in which the cylindrical portion of the rubber member is simply press-fitted into the mounting hole, or a configuration in which the rubber member is integrally attached to the fixing plate by insert molding may be used. In short, the rubber member is preliminarily inserted before the bolts or the like are inserted. What is necessary is just a structure attached to the mounting hole of the fixing plate.

(2) In the above embodiment, the rubber member B
Is formed with an engagement piece B2, which is a bush C
Is pushed out by the push-out piece C2 to engage with the locking edge 6a of the mounting hole 6, but the rubber member is held in the mounting hole by the bush instead of engaging with the mounting hole. It may be a configuration. For example, as shown in FIG. 6, an engagement hole F1 is formed in the rubber member F, and the engagement hole F1 is inserted into the bush G to hold the engagement edge 6a of the attachment hole 6. This is a configuration in which a piece G1 is formed.

(3) In the above embodiment, the connector A is fixed by using the bolt 7, but instead of the bolt, for example, a shaft-shaped member is protruded from the engine body side to It is also possible to adopt a form in which it is fitted and fixed to a rubber member or the like previously assembled in the mounting hole.
In addition, the present invention can be implemented with various modifications without departing from the scope.
