Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a transmission mechanism for an automobile, and more particularly to a dust cover device for a transmission mechanism in which a shift lever and a transmission body are connected by a control rod.

Prior Art When the shift lever and the transmission body are connected by a control rod, the control rod is supported on the floor panel by a dust cover device, and the shift lever on the floor panel is also connected by the dust cover device. The area around the penetration part and around the shift lever swing fulcrum are sealed. This dust cover device includes a housing that is attached to a floor panel, and a socket member that holds a swinging fulcrum of a shift lever and is soft mounted inside the housing, and the soft mount of the socket member is attached to the socket member. This is done by a mount rubber that basically supports the housing, and a dust cover made of rubber bellows that seals around the shift lever penetration part of the floor panel and around the shift lever pivot point. Specifically, this dust cover includes a lower cover disposed across the lower edge of the socket member and the lower side of the swing fulcrum of the shift lever, and a lower cover disposed across the upper edge of the housing and the upper side of the swing fulcrum of the shift lever. It is made up of a covered Atsupakaba. This similar structure is
For example, it is disclosed in Japanese Utility Model Publication No. 53-7460.

Problems to be Solved by the Invention However, in this conventional structure, the dust cover is made up of two members, the lower cover and the upper cover, which is very disadvantageous in terms of molding and assembly, and is a major factor in increasing costs. It is also connected.

SUMMARY OF THE INVENTION In view of the conventional situation, it is an object of the present invention to provide a dust cover device for a speed change operation mechanism, which allows the dust cover to be unified without impairing the sealing performance, thereby achieving a significant cost reduction. It is something.

Means for Solving the Problems In order to achieve the above object, in the present invention, a socket member that holds the swinging fulcrum of the shift lever is attached to a support rod bracket, and this socket member is attached to a floor panel. In a structure in which a mount rubber and a dust cover are soft-mounted on the inside of the housing, a base part where the dust cover is clamped between a socket member and a support rod bracket, and an inner peripheral side of this base part are attached. The first bellows part extends to the lower side of the swinging fulcrum of the shift lever, and the second bellows part extends to the outer circumferential side of the base part and covers the outer circumferential surface of the housing. .

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figs. 1 to 3, numeral 1 denotes a shift lever, and a control rod 2 connected to a striking rod of a transmission (not shown) is connected to the lower end of the shift lever. 3 shows a dust cover device that supports the shift lever 1 on the floor panel 4, and includes a housing 5 attached to the floor panel 4, and a socket that holds the swinging fulcrum 1a of the shift lever 1 and is soft-mounted on the housing 5. It is roughly composed of the member 6. On both sides of the upper edge of the housing 5, a bracket 7 for attaching a mount rubber 11, which will be described later, is provided upright. Reference numeral 8 indicates a support rod disposed across the transmission body (not shown) and the socket member 6, and as the engine (not shown) is driven, the lower end of the shift lever 1 moves forward and backward via the control rod 2. When vibrating, the swing fulcrum 1a is also synchronously vibrated in the front and back direction,
To prevent malfunction of the shift lever 1 in the shift direction. A support rod bracket 9 is fixed to the wrong end of the support rod 8, and the socket member 6 is mounted on the support rod bracket 9 through its lower edge flange 6a to the bolt/nut 1.
It is fixed at 0. Reference numeral 11 denotes a mount rubber that basically soft-mounts the socket member 6 to the housing 5, and a bolt/nut 12 is fixed to the bracket 7 on both sides of the housing 5.The mount rubber 11 has a central part that protrudes downward. A collar 13 is fixed to the collar 13, and a bolt 1 is attached to this collar 13.
The socket member 6 is supported in the housing 5 by inserting the socket member 4 into the support rod bracket 9 and screwing it into a weld nut 15 arranged on the back side of the support rod bracket 9. 16 cooperates with the mount rubber 11 to soft mount the socket member 6 to the housing 5, and also attaches the socket member 6 around the floor panel penetration part of the shift lever 1, specifically around the floor panel penetration part of the housing 5, and the shift lever 1. A dust cover made of a rubber material that seals around the swinging fulcrum 1a of the figure is shown. The dust cover 16 includes a base portion 16a that is clamped between the flange 6a of the socket member 6 and the support rod bracket 9, and a base portion 16a that extends to the inner circumferential side of the base portion 16a and covers the shift lever 1. The first bellows part 16b circumscribes the lower side of the swing fulcrum 1a, and the second bellows part 16c extends to the outer peripheral surface of the base part 16a and covers the outer peripheral surface of the housing 5. In this embodiment, the peripheral flange 16d of the second bellows portion 16c is
It is integrally bonded or fused onto the mounting flange 5a of the housing 5. In addition, the second bellows part 1
An opening 17 is formed in a portion of the housing 5 of 6c corresponding to the bracket 7, and this opening 1
The bracket 7 is inserted through and protrudes from the hole 7.
Furthermore, a holder part 16e for receiving substantially the lower half of the swing fulcrum 1a of the shift lever 1 is integrally molded on the molded base of the first bellows part 16b. It holds the swinging fulcrum 1a.

According to the above embodiment structure, the first bellows portion 16b of the dust cover 16 reliably seals between the socket member 6 and the lower end of the swing fulcrum 1a of the shift lever 1, while the socket member 6 and the housing 5
and between the housing 5 and the floor panel 4 are reliably sealed by the second bellows portion 16c, so splashes, dust, etc. are prevented from entering around the shift lever swing fulcrum 1a or into the vehicle interior. Instead, it is possible to obtain a sealing function that is comparable to that which conventionally uses two members, the lower cover and the upper cover.In fact, by integrating the dust cover 16, the unit cost can be reduced,
As assembly work man-hours, parts management man-hours, etc. can be reduced, significant cost reductions can be achieved.

Effects of the Invention As described above, according to the present invention, the connection between the socket member and the lower side of the shift lever swing fulcrum, between the socket member and the housing, and between the housing and the floor panel is achieved by using only a single dust cover. Since it is possible to create a space between the dust covers, a reliable seal can be achieved, and furthermore, by integrating the dust cover, it is possible to realize a significant cost reduction, which has a great practical effect.
