Description

  The present invention relates to a vehicle speed change operation device that is fixed to a vehicle body and capable of speed change operation.

  BACKGROUND ART A vehicle shift operation device generally has a shift lever (select lever) that can be gripped and operated by a driver. By operating the shift lever, a vehicle shift operation can be performed. Such a vehicle speed change operation device is mainly composed of a bracket that can be fixed to the vehicle body and a cover member through which the shift lever is rotatably inserted, and is constructed by assembling the cover member on the bracket.

  However, conventionally, many vehicle speed change operation devices have been provided in which the bracket is made of metal from the viewpoint of maintaining strength and the cover member is made of resin from the viewpoint of formability. In such a conventional vehicle speed change operation device, a resin cover member is fixed to a metal bracket by screwing, and both can be assembled. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, the conventional vehicle speed change operation device has the following problems because the resin cover member is fixed to the metal bracket by screws. That is, in general, a resin molded product can be molded according to dimensions along the profile surface of the mold, while a metal part subjected to press working or bending processing has a relatively large dimensional error compared to the resin molded product. End up.

  For this reason, when trying to assemble a resin bracket to a metal bracket with a relatively large dimensional error, the dimensional error of both assembly parts will be large, and if it is not assembled with screws, it will be loose. There was a risk of it. When such backlash occurs, there is a problem that chatter noise particularly occurs due to vibration of the vehicle. However, in order to fix the screw, there is a problem that due to the relatively large dimensional error described above, the exact position of the screw hole cannot be guaranteed and screwing work of the screw is required, so that workability is deteriorated.

  On the other hand, if both the bracket and the cover member are made of resin, the dimensional error of the assembling part can be reduced, so that the assembling work can be performed satisfactorily. A claw portion can be provided on the bracket, and the claw portion can be locked and assembled in a hole or notch formed in the bracket. In the case where the claw portion is locked to the hole or the notch, the claw portion can be assembled with one touch, and workability can be improved. However, in the case where a metal bracket is used, there is a possibility that the accurate position of the claw portion with respect to the hole or the notch cannot be guaranteed due to the relatively large dimensional error described above, which makes it difficult to assemble.

  The present invention has been made in view of such circumstances, and even when a resin cover member is assembled to a metal bracket, it absorbs a dimensional error occurring in the assembly portion of both and suppresses backlash. Another object of the present invention is to provide a vehicular speed change operation device that can improve the workability during assembly.

According to the first aspect of the present invention, a metal bracket that can be fixed to the vehicle body, an engaged portion that is integrally extended from the bracket, is formed on the bracket, is mounted on the bracket, and rotates the shift lever. A resin-made cover member that is movably inserted, a leg portion integrally extending from the cover member so as to hang down along one side surface of the engaged portion, and formed at the tip of the leg portion A claw portion that can be engaged with the lower surface of the engaged portion, and extends integrally from the cover member so as to hang along the other side surface of the engaged portion; and The protrusion is formed so as to extend inward from the position of the other side surface of the engaged portion where the protrusion is set, and can be elastically deformed to bend outward and inward with respect to the other side surface. When engaging with the lower surface of the engaging part, it bends outward and the claw part Serial is characterized in that a biasing unit which is a state of being always biased against the other side surface in engagement with the engaged portion.

  According to a second aspect of the present invention, in the vehicle speed change operation device according to the first aspect, a stepped portion is formed on a surface of the leg portion facing the engaged portion, and the distal end side is thick and the proximal end side is thin. In the state where the cover member is assembled to the bracket, a clearance of a predetermined dimension is formed between the base end side of the leg portion and the engaged portion.

  According to a third aspect of the present invention, in the vehicle speed change operation device according to the first or second aspect, the cover member is slid in the front-rear direction of the cover member with respect to the bracket during the assembly process to the bracket. It is characterized in that a clamping portion is formed that clamps while allowing the above.

  According to a fourth aspect of the present invention, in the vehicular speed change operation device according to any one of the first to third aspects, the cover member is attached to the bracket in the state where the cover member is assembled to the bracket. A contact portion that is in contact with the upper surface of the bracket while being biased is integrally formed.

  According to the first aspect of the present invention, when the claw portion is engaged with one side surface of the engaged portion, the urging force by the urging portion is applied to the other side surface of the engaged portion. Even when a plastic cover member is assembled to a bracket made of metal, it is possible to absorb dimensional errors that occur in the assembled parts of both and suppress backlash and improve workability during assembly. it can.

  According to the invention of claim 2, since the clearance of a predetermined dimension is formed between the base end side of the leg portion and the engaged portion in a state where the cover member is assembled to the bracket, the claw portion is engaged. When engaging with the lower surface of the joint portion, the leg portion can be bent outward so that the engaging operation can be performed more smoothly, and the dimensional error between the bracket and the cover member can be more reliably absorbed.

  According to the invention of claim 3, since the cover member is formed on the cover member while allowing the cover member to slide in the front-rear direction with respect to the bracket, the dimensional error in the front-rear direction is reduced in the assembly process to the bracket. While making it absorb, backlash of both can be suppressed further, and workability | operativity at the time of an assembly | attachment can be made still more favorable.

  According to the fourth aspect of the present invention, the cover member is integrally formed with the contact portion that is in contact with the bracket upper surface while being urged in a state where the cover member is assembled to the bracket. It is possible to absorb dimensional errors in the vertical direction, and it is possible to further improve backlash suppression.

  Here, on the back surface side of the cover member 2 in the vehicle speed change operation device according to the present embodiment, as shown in FIG. 3, the front engagement portion 7, the rear engagement portion 8, the auxiliary engagement portion 9, and the clamping The part 10 and the contact part 11 are each formed integrally. The front engaging portion 7 hangs downward from the front side (right side in FIG. 1) of the cover member 2 and can engage with the front engaged portion 5 of the bracket 1. As shown in FIG. 5 (during engagement), the leg portion 7a and the urging portion 7c are provided. In addition, the lower surface 5a of the front side engaged portion 5 protrudes downward in the center to form a central convex portion 5b, and a pair of claws 7b described later engage with both sides of the central convex portion 5b. It is like that.

  In a state where the front engaging portion 7 is engaged with the front engaged portion 5, the leg portion 7a is along one side surface 5c (inner surface) of the front engaged portion 5, as shown in FIG. It hangs down and has a pair of left and right claw portions 7b formed at its tip. The claw portion 7b is in contact with and engaged with the lower surface 5a of the front engaged portion 5 so that the front engaging portion 7 is prevented from coming off from the front engaged portion 5. The leg portion 7a and the claw portion 7b are portions formed integrally with the cover member 2.

  Further, as shown in the figure, a step 7d is formed on the surface of the leg 7a facing the front-side engaged part 5, and the leg 7a has a tip side (the lower side in the figure). The claw portion 7b vicinity side) is thick and the base end side (upper side in the figure) is thin. Thus, a clearance of a predetermined dimension t is formed between the base end side of the leg portion 7 a and the front engaged portion 5, and the distal end side of the leg portion 7 a and the claw portion 7 b are formed on the front engaged portion 5. The side surface 5c and the lower surface 5a are in contact with each other.

  Then, when the front engaging portion 7 is pressed against the front engaged portion 5 in order to assemble the cover member 2 to the bracket 1, the base end side of the thin leg portion 7a is elastically deformed as shown in FIG. The leg portion 7a is bent in the direction of the arrow in the figure, and is pressed as it is in the assembled state shown in FIG. Therefore, when engaging the claw portion 7b with the lower surface 5a of the front engaged portion 5, the leg portion 7a can be bent outward (in the direction of the arrow in FIG. 4) so that the engaging operation can be performed more smoothly.

  On the other hand, in a state where the front engagement portion 7 is engaged with the front engaged portion 5, the biasing portion 7c is, as shown in FIG. 5, the other side surface 5d (outer surface) of the front engaged portion 5. Is integrally extended from the cover member 2 so as to hang down along the other side, and is always biased to the other side surface 5d. That is, the urging portion 7c extends to the inner side (the leg 7a side) from the position (position as shown in the design drawing) of the other side surface 5d of the front side engaged portion 5 where the protruding end is set. In a state where the front side engaging portion 7 is engaged with the engaging portion 5, the urging portion 7 c is bent to the outside of a minute dimension, and the urging portion 7 c is in a state of being in constant contact with the other side surface 5 d. It is.

  Accordingly, when the claw portion 7b is engaged with the one side surface 5c of the front engaged portion 5, the urging force by the urging portion 7c is applied to the other side surface 5d of the front engaged portion 5, Even if the resin cover member 2 is assembled to the metal bracket 1, it is possible to absorb the dimensional error generated in the assembly portion of both and suppress the play and to improve the workability at the time of assembly. can do. That is, even when the front engaged portion 5 is outside the set position due to a dimensional error (right side in FIGS. 4 and 5), the application of the urging force by the urging portion 7c is maintained. The backlash is suppressed.

  Further, since the base end side of the leg portion 7a is thin and easy to bend, in addition to the urging force by the urging portion 7c, the metal bracket 1 is also covered with a resin cover member by the bending of the leg portion 7a. The dimensional error at the time of assembling 2 can be absorbed. That is, even when the front-side engaged portion 5 is inward of the set position (left side in FIGS. 4 and 5) due to a dimensional error, the leg portion 7a is bent and engaged by the claw portion 7b. Can be maintained.

  As shown in FIGS. 3 and 7, a rear engagement portion 8 having substantially the same function as the above-described front engagement portion 7 is formed on the back surface at the rear end of the cover member 2. The rear engagement portion 8 is mainly composed of a leg portion 7a and a biasing portion 7c, and a claw portion 7b ′ formed at the tip of the leg portion 7a is paired like the claw portion 7b described above. Although not separated, it engages with the lower surface of the rear engaged portion 6 of the bracket 1 (see FIGS. 8 and 10) to prevent it from coming off.

  In addition, a sandwiching portion 10 is integrally formed at a position corresponding to the front engagement portion 7 on the back surface at the rear end of the cover member 2. As shown in FIG. 3, the sandwiching portion 10 is composed of a pair of ribs 10 a and 10 b extending in the extending direction (front-rear direction) of the bracket 1, and the sandwiched portion 12 of the bracket 1 is inserted into the separated portion. It can be pinched. Thereby, in the process of assembling the cover member 2 to the bracket 1, the cover member 2 can be held while allowing the slide of the cover member 2 in the front-rear direction with respect to the bracket 1. Can be further suppressed, and the workability during assembly can be further improved.

  Furthermore, a contact portion 11 is formed on the back surface at the rear end of the cover member 2. As shown in FIG. 3, the contact portion 11 is mainly composed of a beam portion 11b formed by the slit 11a and a convex portion 11c protruding downward from the approximate center of the beam portion 11b. As shown in FIG. 9, in a state where the cover member 2 is assembled to the bracket 1, the convex portion 11 c comes into contact with the upper surface of the bracket 1 while being urged.

  That is, in the state in which the cover member 2 is assembled to the bracket 1, the convex portion 11c is formed so that the beam portion 11b is bent upward, and the convex portion 11c is always formed by the restoring force of the beam portion 11b. The upper surface of the bracket 1 is pressed. Thereby, the dimension error of the up-down direction with respect to the bracket 1 of the cover member 2 can also be absorbed, and suppression of play can be improved further.

  According to the above-described vehicle speed change operation device, the engaging portion (including the auxiliary engaging portion 9) including the front engaging portion 7 and the rear engaging portion 8 is the front engaged portion 5 and the rear side of the bracket 1. Since the cover member 2 is assembled to the bracket 1 by engaging with the engaged portion 6 or the like, the work can be performed with one touch and the workability at the time of assembly can be improved as compared with the assembly using screws or the like. it can. At the same time, since the urging force by the urging portion 7c is applied to the engaged portion, the backlash in the front-rear direction of the cover member 2 with respect to the bracket 1 can be suppressed, and chatter noise due to the backlash can be effectively prevented. Can be prevented.

  Although the present embodiment has been described above, the present invention is not limited to this, and may have only one of the front engagement portion 7 and the rear engagement portion 8, for example. Alternatively, the leg portion 7a may be extended along the other side surface 5d of the front engaged portion 5 and the urging portion 7c may be extended along the one side surface 5c. Further, in place of the contact portion 11 including the beam portion 11b and the convex portion 11c, a contact portion 13 as shown in FIGS. 11 and 12 may be used.
