Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem in that on assembling a compression member after assembling a compressed piece, there are cases that the pressing down amount of the compressed piece exceeds its elastic limit and develops plastic deformation.  <P>SOLUTION: The compressed piece (plate spring) 17 is lift-supported by the contact at a position of an outer direction from notched edge ends 13, 13 of a supporting leg-receiving part 7 on a movable side.
