Combined operating mechanism

摘要

The present invention provides a high-quality combined operating mechanism capable of putting a brake on up-and-down movements of an operating member which is pressed and rotated.

A protruding wall 11b with a rack 14 and a heart-shaped cam groove 15 is vertically arranged in a rotational member 11 that is rotatably supported by a housing 1. An operating member 16 is spline-coupled to the rotational member 11 via a coil spring 17 so as to be movable in up and down directions with respect to the rotational member. A pin holder 18 and a rotary damper 19 are supported by a supporting wall 16b that is vertically arranged in the operating member 16. Also, a sliding end 21a of the pin holder 18 is engaged with the heart-shaped cam groove 15, thereby constructing a push-lock mechanism to lock the operating member 18 at its lowered position. A pinion 26 of the rotary damper 19 meshes with the rack 14, which forms operation resistance applying means that puts a brake on up-and down movements of the operating member 16.
