It is fixed to the holding piece portion 34 . The motor main body 22 has a circuit board 27 screwed to the end face 22b opposite to the end face 22a from which the rotary drive shaft 23 protrudes (see FIG. 5). When the steering wheel W is steered straight ahead, the rotary drive shaft 23 is arranged along the left-right direction, as shown in FIG.

When the vibrating device 20 is attached to the mounting seat 8, the circuit board 27 protrudes obliquely downward toward the boss portion B from the inner peripheral side of the mounting seat 8 along the spoke core member 4B in the vehicle-mounted state. Then, it is arranged so that the corresponding lead wire is extended obliquely upward from the boss portion B side and fastened to the connector 27a at the tip.

The weight 25 attached to the rotary drive shaft 23 has a plate-like shape having a thickness of approximately 1/3 circle, and is provided with a fitting hole 25a into which the rotary drive shaft 23 is fitted at an eccentric position.

As shown in FIGS. 3 to 6, the mounting bracket 30 is made of sheet metal, has a mounting piece portion 31 extending in the left-right direction in a strip shape, and extends bent from an end portion 31e of the mounting piece portion 31 to hold the vibration motor 21. and a holding piece portion 34 . In the case of the first embodiment, the holding piece portion 34 is bent in the orthogonal direction from the end portion 31e of the mounting piece portion 31 and extends downward in the substantially orthogonal direction of the mounting seat 8 (downward when mounted on the vehicle). (Note that FIGS. 3 to 6 are illustrated as being turned over from the vehicle-mounted state). A through hole 34a is formed in the holding piece portion 34, through which the rotary drive shaft 23 of the vibration motor 21 is passed. A screw 36 for mounting the motor main body 22 is inserted through the holding piece portion 34 from the surface on the mounting piece portion 31 side and screwed into the motor main body 22 at the peripheral edge of the through hole 34a.

The mounting piece 31 has a circular insertion hole 32 through which a screw 39 for fastening the screw 39 to the mounting seat 8 is inserted. It is formed so as to penetrate vertically. A circular through-hole 42 is provided between the insertion hole 32 and the holding piece 34 in the attachment piece 31 .

After that, the rotation driving shaft 23 is fitted into the fitting hole 25a, and the outer peripheral side of the fitting hole 25a is crimped so as to press the rotation driving shaft 23, and the weight 25 is attached to the rotation driving shaft 23. The work of attaching the vibration motor 21 to the bracket 30 is completed, and the assembly of the vibration device 20 is completed.

The assembled vibrating device 20 is mounted on a predetermined jig with the steering wheel main body 1 turned over from the vehicle-mounted state with the mounting seat 8 facing upward. Then, as shown in FIGS. 7 and 8, the through hole 42 is provided with a through hole 42 so that the insertion hole 32 of the mounting piece portion 31 in the mounting bracket 30 of the vibrating device 20 is aligned with the mounting hole 10 of the mounting seat 8 . 52, the mounting piece portion 31 is disposed on the upper surface side of the flat portion 9 of the mounting seat 8. As shown in FIG. At this time, if the through projection 52 is passed through the through hole 42, the projection 53 of the through projection 52 can be engaged with the peripheral edge 43 of the through hole 42, thereby exhibiting the function of the lifting restricting means 91. , the weight of the motor main body 22 restricts the attachment piece 31 from lifting from the attachment seat 8 such that the insertion hole 32 is separated from the attachment hole 10 , and the operator can release the vibration device 20 . However, the insertion hole 32 does not come off from above the mounting hole 10.例文帳に追加Therefore, the screw 39 can be easily inserted into the mounting hole 10 through the insertion hole 32, and then the screw 39 can be simply turned in the screwing direction. When the screw 39 is tightened, even if the mounting piece 31 tries to rotate around the insertion hole 32 in the direction of rotation when the screw 39 is tightened, the inner peripheral surface 42a of the through hole 42 as the mounting recess 41 does not move. Since the rotation of the mounting piece portion 31 is restricted by the outer peripheral surface 52a of the through projection portion 52 as the assembly projection portion 51 (see B in FIG. 7), the rotation restriction means 90 exerts its action. , the screw 39 can be smoothly tightened, the mounting piece portion 31 can be mounted and fixed to the mounting seat 8 , and the vibrating device 20 can be mounted to the mounting seat 8 of the ring core member 5 .

Since lifting from the hole 10 is restricted (see two-dot chain line in FIG. 8B), the work of inserting the screw 39 into the mounting hole 10 through the insertion hole 32 is facilitated. Further, since the rotation restricting means 90 restricts the rotation of the mounting piece portion 31 when the screw 39 is fastened to the mounting seat 8, after the screw 39 is inserted through the insertion hole 32 into the mounting hole 10, the screw 39 can be simply , the screw 39 can be fastened to the mounting hole 10 without firmly holding the mounting bracket 30 separately by simply turning the screw 39, and the fastening work of the screw 39 can be efficiently performed, and the mounting bracket 30 can be attached to the mounting seat. The work to be attached to 8 can be easily performed.

When the screw 39 is tightened, it abuts against the side surface 31c to restrict the rotation of the attachment piece 31. Therefore, the peripheral wall portion 13 and the side surface 31c may constitute a rotation restricting means.

That is, like the steering wheel WB shown in FIG. 10, the rotation restricting means 90B has a restriction portion (restriction wall) 60 formed of a part of the peripheral wall portion 13 that restricts the side surface 31c of the mounting piece portion 31B during screwing. It may be configured to be arranged on the mounting seat 8B side. The peripheral wall portion 13 having the restricting portion 60 is provided on the covering portion 12 extending from the covering layer 6 and covering the ring core member 5 .

In this steering wheel WB, when the mounting piece portion 31B of the mounting bracket 30 is arranged on the mounting seat 8B, the mounting piece portion 31B is locked by the locking portion 61 of the restricting portion 60 while the mounting piece portion 31B is locked. The lifting of the mounting piece portion 31B and the rotation of the mounting piece portion 31B during screwing are restricted by a simple assembly work of arranging the side surface 31c so as to face the restricting portion 60 on the side of the mounting seat 8B. As a result, the assembly work for arranging the mounting piece portion 31B of the mounting bracket 30 on the mounting seat 8B can be easily performed.

Although the engaging portion 61 is formed of the covering portion 12 having elasticity, it is formed so as to ensure an engaging force capable of restricting the lifting of the mounting piece portion 31B.

A screw 39 inserted through the insertion hole 32 of the mounting bracket 30 is fastened to the mounting seat 8D of the second embodiment on the right end side (the left end side in FIG. 14) in the same manner as in the first embodiment. A mounting hole 10 is formed for this purpose, and a through protrusion 52 forming an assembly protrusion 51 protrudes near the center in the left-right direction. The vicinity of the mounting hole 10 of the mounting seat 8</b>D forms a flat portion 9 that abuts against the rear surface 31 a on the contact side of the mounting piece portion 31 . However, in the vicinity of the mounting hole 10, when the screw 39 is tightened, the contact state between the mounting piece portion 31 and the mounting seat 8 is a metal touch so as to enhance the fastening force. The vicinity of the penetrating convex portion 52 is a covered flat portion 9b provided with the covering layer 6 covering the core material 4C (see FIGS. 15 to 17).

In the second embodiment, the coating layer 6 of the flat coating portion 9b extends from the portion covering the ring core 5 so as to cover the spoke core 4B2, and further extends to cover the mounting seat 8D. It is formed from the covering portion 12D. The covering portion 12D is arranged on the lower surface side of the mounting seat 8D (which is the lower surface side in the vehicle-mounted state) so as to fill the concave portion 4b provided in the connecting rod portion 4a.

Further, the penetrating convex portion 52 of the second embodiment also covers the core protrusion 11D extending from the core 4C and the covering portion 12D extending from the covering layer 6 in the same manner as in the first embodiment. Let it be composed. Furthermore, similarly to the first embodiment, the covering portion 12D is provided with a protrusion 53 protruding like a flange toward the attachment hole 10 near the tip of the core material protrusion 11D.

Of course, in the second embodiment as well, the inner diameter dimension of the through hole 42 of the mounting piece portion 31 and the outer diameter dimension of the through convex portion 52 of the mounting seat 8D are set so as to fit each other. Rotation restricting means 90 for restricting the rotation of the mounting piece portion 31 when the screw 39 is tightened by constituting the assembly concave portion 41 and the assembly convex portion 51 which are assembled so as to fit each other when the piece portion 31 is arranged. Configure. Furthermore, in the case of the second embodiment as well, the protrusion 53 of the through protrusion 52 inserts the through protrusion 52 into the through hole 42 while disposing the mounting piece 31 from above on the mounting seat 8D facing upward. After that, the peripheral edge 43 of the through hole 42 can be locked. That is, when the mounting piece portion 31 is arranged on the mounting seat 8D from above, the lifting of the mounting piece portion 31 from the mounting seat 8D due to the tilting of the holding piece portion 34 holding the vibration motor 21 is prevented by the peripheral edge of the through hole 42. 43 is regulated by engaging the protrusion 53 (see the two-dot chain line in FIG. 15). Therefore, the protruding portion 53 of the penetrating protrusion 52 and the through-hole peripheral edge 43 constitute a lifting restricting means 91 that restricts the lifting of the mounting piece portion 31 from the mounting seat 8D. Furthermore, in the second embodiment, the through-hole 42 and the through-projection 52 also constitute the rotation restricting means 90, as described above, and constitute the lifting restricting means 91 and the combined restricting means 92. ing.

Further, in the second embodiment, a side surface 31c in the width direction (rear side in the figure) of the mounting piece portion 31 around the mounting seat 8D is provided so as to restrict the rotation of the side surface 31c when the screw 39 is tightened. A regulating portion 60D is provided. The restricting portion 60D is provided with a core projection 14 projecting from the core 4 (4B2) disposed around the mounting seat 8D. Specifically, the restricting portion 60D is configured such that the core protrusion 14 is covered with the covering portion 15 extending from the covering portion 12D.

Therefore, in the second embodiment, when the screw 39 is tightened, the restricting portion 60D comes into contact with the side surface 31c of the mounting piece portion 31 of the mounting bracket 30, and the rotation of the mounting piece portion 31 can be restricted. 31c constitute a rotation restricting means 60D.

In the second embodiment, since the restricting portion 60D of the rotation restricting means 60D is configured by providing the core projection portion 14 made of the core material 4B2, the restricting portion composed only of the covering portion 12 of FIG. 60, the strength can be improved, and the rotation of the mounting piece portion 31 can be stably regulated when the screw 39 is tightened.

In addition, in the restricting portion 60D of the second embodiment, the case where the core protrusion 14 is covered with the covering portion 15 extending from the covering layer 6 is shown. and may be formed.

Furthermore, in the second embodiment, two types of rotation restricting means, the restricting portion 60D and the through protrusion 52, are provided, and the restricting portion 60D is located in the vicinity of the side of the through hole 42 through which the through protrusion 52 penetrates. is disposed so as to regulate the side surface 31c of the mounting piece portion 31 of the . Specifically, the restricting portion 60D is arranged on the side surface 31c side of the attachment piece portion 31, and in a direction along the longitudinal direction of the attachment piece portion 31 (the direction connecting the attachment hole 32 and the through hole 42), with respect to the through hole 42. A wrap amount r (see FIG. 4) is provided so as to wrap. Therefore, when the through hole 42 of the mounting bracket 30 is passed through the through hole 42 of the mounting bracket 30 so that the through hole 32 is aligned with the mounting hole 10, and the mounting piece 31 is disposed on the mounting seat 8D, the mounting piece 31 is The side surface 31c is also arranged at a predetermined position while being restricted in position so as to be guided by the restricting portion 60D. Therefore, even if the mounting piece portion 31 attempts to rotate clockwise or counterclockwise around the through projection portion 52 in a state in which the through projection portion 52 is passed through the through hole 42 , the side surface of the mounting piece portion 31 is 31c is restricted near both lateral edges 60a and 60b of the restricting portion 60D, and their rotation is restricted. That is, since the insertion hole 32 of the mounting piece portion 31 is arranged without being displaced from above the mounting hole 10, if the mounting piece portion 31 of the mounting bracket 30 is arranged on the mounting seat 8D, it will be restricted. The portion 60D and the through protrusion 52 prevent the insertion hole 32 from being displaced from the mounting hole 10, thereby facilitating the subsequent work of inserting the screw 39 into the mounting hole 10 via the insertion hole 32. The mounting work of the bracket 30 to the mounting seat 8D can be easily performed.

In addition, in the steering wheel W of the first embodiment, the mounting seat 8 for mounting the vibration device 20 is provided at the portion of the core material 5 of the ring portion R.

The thickness dimension in the vicinity of R, particularly the thickness dimension T from the ring surface RP, becomes large (see FIG. 4), and the appearance of the vicinity of the ring portion R tends to deteriorate. If the mounting seat 8 is provided at the portion of the core member 5 of the ring portion R while considering this point, the mounting seat 8 is disposed while providing the core member 5 with a concave portion. In order not to reduce the strength of the core member 5, it is necessary to provide a recess for the mounting seat, which is troublesome.

On the other hand, when the mounting seat is provided in the core part of the spoke, there is no need to consider the installation space or to provide a concave portion in the core material that affects the strength reduction. , mounting seats can be provided.

However, as in the steering wheel WD of the second embodiment, when the mounting seat 8D is provided at the portion of the core member 4 (4C) of the spoke portion S (SB), the installation space may be taken into consideration and the strength may be lowered. It is possible to easily dispose the mounting seat 8D without adopting a configuration in which the core member 4 is provided with an influential concave portion.

When the mounting seats 8D are arranged on the spokes S, in the second embodiment, the vibration device 20 is mounted on the spokes SB on the rear side, but mounting seats are provided on the left and right spokes SFL and SFR. A vibrating device may be provided.
