Abstract

A collar member formed as a hollow cylinder having an opening at one end into which a mounting pin member of the damper unit is inserted, and which is secured to a cored bar member, a seat part provided at the other end of the collar member in which the insertion side tip of the pin is seated, a positioning groove part formed on the collar member between the seat part and the opening, a locking groove part formed on the pin that is positioned in the positioning groove part when the insertion side tip is seated in the seat part, and a spring member provided on the cored bar member inserted through the positioning groove part that is elastically locked by the locking groove part when the insertion side tip is seated in the seat part and retains the pin.

First claim

1 . A mounting and securing structure for the damper unit of a steering wheel, comprising: an airbag module as the damper mass, a damper unit to dampen the vibrations of the steering wheel, and in order to incorporate the damper unit between the steering wheel and the airbag module, being provided with a mounting pin member for the damper unit part of either the steering wheel or the airbag module,
a collar member formed in a hollow cylinder with an opening for on one end in the length direction where the mounting pin member I inserted and is provided secured on the support part, a seat part provided on other end in the length direction of the collar member where an insertion side tip of the mounting pin member is seated, a positioning groove part positioned on the collar member between the seat part and the opening and formed in a direction in an orientation intersecting the length direction, a locking groove part formed on the mounting pin member which becomes positioned on the positioning groove part when the insertion side tip is seated in the seat part, and a spring member provided on the support part inserted through the positioning groove part and is elastically locked by the locking groove part when the insertion side tip is seated in the seat part and retains the mounting pin member.

2 . The mounting and securing structure for the damper unit of the steering wheel according to claim 1 , wherein the seat part comprises a plurality of lever pieces protruding cantilevered from an inner surface of the hollow cylindrical collar member.

3 . The mounting and securing structure for the damper unit of the steering wheel according to claim 1 , wherein the seat part is provided with a grip for grasping the insertion side tip of the mounting pin member.

4 . The mounting and securing structure for the damper unit of the steering wheel according to claim 2 , wherein the seat part is provided with a grip for grasping the insertion side tip of the mounting pin member.

5 . A steering wheel provided with the mounting and securing structure for the damper unit of a steering wheel according to claim 1 .

6 . A steering wheel provided with the mounting and securing structure for the damper unit of a steering wheel according to claim 2 .

7 . A steering wheel provided with a mounting and securing structure for the damper unit of a steering wheel according to claim 3 .

8 . A steering wheel provided with a mounting and securing structure for the damper unit of a steering wheel according to claim 4 .
