  With respect to the steering wheel main body 12, the module 11 aligns each insertion opening 44 and each hook 37 and pushes in from the front side, thereby holding the holding portion 84 of the wire 45 as shown in FIG. When the hook 37 pushes open the holding portion main bodies 84a and 84a and elastically climbs over the holding portion main bodies 84a and 84a, and the holding portion main bodies 84a and 84a of the holding portion 84 of the wire 45 are restored and deformed, the holding portion 84 is restored. Engages with the locking surface 42 of the recess 41 of the hook 37 (FIG. 4). As a result, the module 11 is engaged with the steering wheel main body 12 at two locations on both sides and supported to prevent the module 11 from coming off.

  Therefore, the position of the module 11 is regulated in the front-rear direction, the up-down direction, and the left-right direction relative to the steering wheel main body 12, and the hooks 37 are prevented from coming off in the front direction by the wires 45.

  Further, in this state, the module 11 is configured such that the horn spring 46 is interposed between the back surface of the base plate 21 of the module 11 and the boss core 72 of the boss portion 62 of the steering wheel body 12 so that the steering wheel 12 The module 11 is guided to the steering wheel main body 12 along the front-rear direction by the hooks 37.

  For example, the steering wheel 10 provided with the module 11 is configured to be attached to the steering shaft by performing electrical wiring on the contact portion of the inflator.

  The steering wheel 10 configured as described above is operated when the occupant in the driver's seat holds the rim portion 61 and rotates. Further, by pushing the airbag cover 22 of the module 11 that also serves as a pushing portion against the urging load of each horn spring 46, the hook 37 and the insertion opening 44 are fitted to each other. When the module 11 is guided relatively forward (FIG. 4) and one of the movable contacts contacts the fixed contact, the horn device on the vehicle body side is blown.

  Further, in the event of a frontal collision of the vehicle, gas is rapidly injected from the inflator into the inside of the airbag, and the airbag stored in a folded state is rapidly inflated. Then, due to the inflation pressure of the airbag, the airbag cover 22 is cleaved along the tear line to form the airbag's protruding opening, and the airbag protrudes from the protruding opening and is inflated and deployed in front of the occupant. Restrain and protect. At this time, the module 11 is held by the steering wheel body 12 against an impact when the airbag is inflated and deployed because each hook 37 is mainly locked by the wire 45.

  On the other hand, when removing the module 11 from the steering wheel body 12, the pressed portion 82b of the operated portion 82 of the wire 45 is pushed upward, that is, toward the embossed portion 77 from the front surface of the cover body using a jig or the like. The embossed portion 77 is deformed so as to expand to the left and right along the outer shape of the embossed portion 77 as the opposed portions 82a and 82a that come into contact with the outside of the embossed portion 77 are pushed in, and finally pass through the opposed portions 82a and 82a. The pressed portion 82b contacts with the embossed portion 77 and deforms so as to expand to the left and right depending on the width of the embossed portion 77 (FIGS. 1A to 1C). For this reason, the arm portions 81, 81 connected to the operated portion 82 at a predetermined angle start from the contact portion with the embossed portion 77, the right arm portion 81 is on the right side, and the left arm portion 81 is on the left side. In addition, each of the operated parts 82 rotates around the pressed part 82b. This rotation is guided along the front surface 72a of the boss core 72 by moving the held portion 85 of each arm portion 81 along the slit 75c (FIG. 3). As a result, the left and right holding portions 84, 84 move away from the left and right insertion openings 44, 44 in the opposite directions, and the locking surfaces 42 of the hooks 37, 37 located at the insertion openings 44, 44. , 42, the locking is released, and the module 11 is removed from the steering wheel body 12.

Has been. Therefore, each arm portion 81 is bent along the outside of each embossed portion 77 and connected to the connecting portions 82d and 82d.

  Then, as in the first embodiment, the module 11 is pushed into the steering wheel main body 12 by aligning each insertion opening 44 and each hook 37 from the front side and pushing each module 11 from the front side. The portion 84 engages with the locking surface 42 of the recess 41 of each hook 37, and the module 11 engages with the steering wheel body 12 and is supported to prevent it from coming off.

  On the other hand, when removing the module 11 from the steering wheel main body 12, from the front surface of the cover body, a jig or the like is inserted into the operated portion main body 82c of the operated portion 82 of the wire 45, and the operated portion main body 82c is moved upward. , The connecting portions 82d and 82d are pushed upward integrally with the operated portion main body 82c. For this reason, the arm portions 81, 81 connected to the connecting portions 82d, 82d expand left and right starting from the embossed portion 77, that is, the right arm portion 81 is on the right side and the left arm portion is on the right side. 81 is deformed so as to rotate to the left (FIGS. 7A to 7C). As a result, the left and right holding portions 84, 84 move away from the left and right insertion openings 44, 44 in the opposite directions, and the locking surfaces 42 of the hooks 37, 37 located at the insertion openings 44, 44. , 42, the locking is released, and the module 11 is removed from the steering wheel body 12.

  In this way, the wire 45 is deformed by the pushing operation of the operated portion 82, and the arm portions 81 are paired starting from the embossed portions 77, 77 in the direction in which the holding portions 84, 84 are separated from the hooks 37, 37. , 81 can be rotated, and the holding and holding of the holding portions 84 and 84 provided in the arm portions 81 and 81 that form a pair can be more reliably released by a simple operation. The same effects as those of the first embodiment can be obtained.

  Specifically, in the present embodiment, the operated portion 82 includes a loop-shaped operated portion main body 82c positioned between the embossed portions 77, 77 corresponding to the arm portions 81, 81, and the operated portion It is composed of connecting portions 82d and 82d that are connected to both end portions of the main body 82c and extend toward the embossed portions 77 and 77, and the arm portions 81 and 81 are bent and connected along the outside of the embossed portions 77 and 77. Since it is connected to the parts 82d and 82d, the arm parts 81 and 81 can be easily moved from the hooks 37 and 37 in the left-right direction starting from the embossed parts 77 and 77 simply by pushing the operated part main body 82c.
