In this case, the displacement of the diaphragm portion 14 becomes larger than in the normal case, and most of the projection portion 20 becomes elastically crushed due to the reaction force. As a result, the upper surface of the restricting portion 19 comes into contact with the lower surface of the supporting portion 13, and the movement of the protruding portion 20 is prevented, and further deformation of the diaphragm portion 14 does not occur. Note that when the force applied to the blade portion 18 in the direction of arrow A is released, the protrusion portion 20 is elastically restored so as to protrude upward.
