Abstract

See full text

A lever 40 is supported by a lever supporting portion 41. Through a first pivoting member 52, the lever 40 is urged by a reaction force stabilization spring 54, a first spring 55 and a second spring 56. The downward displacement of a second pivoting member 53 is restricted by a fixed supporting member FR. If the urging force of the first spring 55 exceeds the urging force of the second spring 56, the second pivoting member 53 is displaced upward. A contact member which is in contact with the first pivoting member 52 and the second pivoting member 53 to produce friction force is also provided.
