Holding structure of intervening member, intervening member, and wobbling-prevention member

Abstract

A holding structure of an intervening member is provided for preventing the dropping-out of a wobbling-prevention member at an assembly time, and to extend an applicable range of rigidity of the intervening member to a low-side range. A baffle plate (2) is intervened between a torque converter housing wall (5) and an transmission case (3) (intermediate wall (6)), and a wobbling-prevention member (39) is a holding structure of the intervening member interposed between the baffle plate and the torque converter housing wall in a compressed state. Under the precondition, a bottom portion (31a (37a)) of a concave portion (31 (37)) is clamped between a head portion (41) and a bulging portion (42) of the wobbling-prevention member, so that the wobbling-prevention member is held in the bottom portion of the concave portion reliably even during the operation. Also, an inside of the head portion of the wobbling-prevention member is hollow, so when the head portion is crushed and deformed, the air inside the head portion is discharged to the outside through an annular gap (43) to reduce a compressive load relative to the baffle plate.

Description

technical field [0001] The present invention relates to a holding structure of an intervening member, an interposing member for the holding structure of the intervening member, and a sway preventing member for preventing wobbling of the intervening member. Background technique [0002] As the holding structure of the intervening member, there is a holding structure in which the intervening member is interposed between the first member and the second member. For example, in Patent Document 1, it is proposed that one end of the intervening member is attached to the first member in consideration of assembly, and on the other hand, the other end of the intervening member is provided with a rubber cover. The protruding end portion is fitted with the fitting portion formed on the second member. [0003] In addition, in the holding structure of the intervening member, there is a holding structure in which the intervening member is only held between the first member and the second ...

AI Technical Summary

Problems solved by technology

[0006] However, in the holding structure of the above-mentioned intervening member, in general, a rubber packing is used as the rattling prevention member, and the rubber packing is only temporarily fitted (temporarily fixed) in the recess formed in the intervening member, and the During the assembly work in which the intervening member is interposed between the first member and the second member, the rubber packing may come off from the recess of the intervening member

Therefore, when the rubber packing falls off, it is necessary to pick up the rubber packing and reassemble it again, and the fall of the rubber packing reduces workability.

[0007] In addition, when assembling the first member, the second member, and the intervening member, in order to restrict the rattling of the intervening member between the first member and the second member, the rubber packing as the rattling prevention member is compressed until it reaches a predetermined compressed state. , but in order to bring the rubber gasket into the specified compressed state, a very high compressive load is required

Therefore, when a rubber packing is used as the shaking prevention member, a member with high rigidity is required as an intervening member, and it is difficult to use an intervening member with low rigidity.
