When the contact 421 moves in the mounting hole along the first direction, the first groove wall 5021 presses the first side surface 301 to generate a pressing force in the first direction, and the second groove wall 5022 presses the second side surface 302 to generate a pressing force in the second direction. So as to shear the elastic member 300, generate deformation and store elastic potential energy. In order to allow the elastic member 300 to deform more, an area of the first groove wall 5021 abutting against the first side surface 301 is smaller than an area of the second groove wall 5022 abutting against the second side surface 302.
