The position is restricted. In this state, the hooks 43 are reliably prevented from coming off in the front direction by the hook engaging portions 90, 90, 98, and the module 12 is prevented from being unexpectedly detached from the steering wheel body 11.

  In this state, the steering wheel main body 11 is guided along the front-rear direction by the hooks 43.

  Further, in each unit portion 34, each coil spring 44 is interposed between a mounting member 42 fixed to the steering wheel body 11 (boss core metal 26) side and a collar 45 fixed to the module 12 (base plate 65) side. The movable contacts 77 of the module 12 are supported in a state of being separated from the fixed contacts 36 of the steering wheel body 11 by the urging force of the coil springs 44.

  Further, the steering wheel 10 including the module 12 is configured to be attached to the steering shaft by, for example, performing electrical wiring on a contact portion of the inflator 69 or the like.

  The steering wheel 10 configured as described above is operated when the occupant in the driver's seat holds the rim portion 15 and rotates. The occupant is fixed to the steering wheel body 11 (boss core 26) side by pushing the airbag cover 66 of the module 12 that also serves as a pushing portion against the urging force of each coil spring 44. When each collar 45 moves integrally with the module 12 with respect to each hook 43 and any one of the movable contacts 77 contacts the fixed contact 36, the horn device on the vehicle body side is blown.

  On the other hand, in the event of a frontal collision of the vehicle, gas is rapidly injected into the airbag 67 from the inflator 69, and the airbag 67 folded and stored rapidly expands. Then, due to the inflation pressure of the airbag 67, the airbag cover 66 is cleaved along the tear line to form a projection port of the airbag 67. The airbag 67 projects from the projection port and is inflated and deployed in front of the occupant. In addition, the occupant is restrained and protected.

  Even when, for example, engine vibration during idling or vibration when traveling on a rough road is transmitted to the steering wheel body 11, the outer peripheral surface 62a of the collar 45 is in contact with the inner peripheral surface 102a of the wall 102. Since it is held, the movement of each unit 34 in the direction intersecting the axial direction of the hook 43, that is, the direction deviating from the opening 101 is restricted. That is, one of the boss metal core 26 of the steering wheel body 11 and the base plate 65 of the module 12, in the present embodiment, the other one of the boss metal core 26 and the base plate 65 penetrating the base plate 65 of the module 12, the present implementation In this embodiment, the other end of the boss mandrel 26 of the steering wheel body 11 and the base plate 65 of the module 12 with respect to the opening 101 that expands toward the boss mandrel 26, in the present embodiment, the boss of the steering wheel body 11 The collar 45 of the unit portion 34 provided on the core metal 26 is fitted, and the wall portion 102 is brought into contact with the fitted collar 45 so that the position in the direction intersecting the axial direction of the collar 45 is set. By restricting, compared to a configuration in which a pin or the like for restricting the position of the module 12 with respect to the steering wheel main body 11 is provided, the configuration from the opening 101 due to vibration is simpler The deviation of the error 45 can be reliably prevented. As a result, generation of noise caused by contact between the excessively vibrated module 12 and the steering wheel main body 11 and detachment of the module 12 with respect to the steering wheel main body 11 can be more reliably prevented.

  That is, each opening 101 is formed in a tapered shape so as to expand to the side where the collar 45 or the hook 43 is inserted so that the collar 45 or the hook 43 can be easily inserted. The shape of the collar 45 to be joined is easy to shift. Therefore, by projecting the wall 102 around the opening 101, the collar 45 is securely attached to the opening 101 while maintaining ease of insertion of the collar 45 and the hook 43 into the opening 101. Can be prevented from slipping.

  Specifically, FIG. 7 shows the result of test evaluation by inputting 2.1 G vibration assuming rough road traveling to the steering wheel 10 described above. As shown in FIG. 7, in the example corresponding to the present embodiment, the amplitude amount of the module 12 is suppressed as in the comparative example in which the module is fixed to the steering wheel with bolts.

  Further, as the anti-slip portion for preventing the collar 45 from shifting from the opening portion 101, the wall portion 102 is provided as a wall portion 102 protruding from the outer edge portion of the opening portion 101 so as to face the insertion direction of the hook 43 with respect to the opening portion 101 Since the wall portion 102 (anti-slip portion) can be easily formed by using a mold for forming the base plate 65 by bringing the portion 102 into contact with the side surface (outer peripheral surface 62a) of the collar 45, a simpler configuration Thus, the displacement of the collar 45 from the opening 101 due to vibration can be prevented more reliably.

  In the first embodiment described above, for example, as in the second embodiment shown in FIG. 8, the mounting opening 33 is formed in the base plate 65 and the unit portion 34 is attached to the module 12, and the opening 101, Even if the wall 102 and the wires 84 and 85 are formed on the boss core 26 of the steering wheel body 11, the same effect can be obtained.

  In addition, if the wall 102 is in contact with the outer peripheral surface 62a of the collar 45 to prevent slippage, the wall 102 is partially formed on the peripheral edge of the opening 101 instead of being continuous with the entire circumference of the opening 101. It may be a rib shape.

  Furthermore, in each of the above-described embodiments, for example, as in the third embodiment shown in FIG. 9, instead of the wall portion 102, the inner wall portion 101 a of each opening portion 101 is continuously connected to the opening portions 101. It is also possible to form an inner wall portion 125 that is a cylindrical surface as an anti-slip portion that contacts the outer peripheral surface 62a of the contact holding portion 62 of the collar 45 along the front-rear direction that is the insertion direction of the hook 43. Even in this case, the inner wall 125 (anti-slip part) can be easily formed by simply changing the shape of the opening 101 of the mold when the base plate 65 or the boss core 26 is molded. The effects similar to those of the above-described embodiments can be achieved, such as the displacement of the collar 45 from the opening 101 due to vibration can be more reliably prevented.

  The engaging member (wire) is composed of one for the left and right sides of the steering wheel main body 11 and the module 12 and one for the lower part. For example, one engaging member (wire) is arranged for each side. It can also be set as the three structure which has arrange | positioned one for lower parts.

  In addition, the steering wheel 10 is not limited to the configuration including the three spoke portions 17 and can be applied to a configuration including, for example, two or four spoke portions 17.

  Further, as the module 12, for example, a pad body containing an impact absorber can be used instead of the airbag device.

  The present invention can be suitably used, for example, as a steering wheel for an automobile.
