This is because if the contact pressure is high, the contact friction also increases, which may make it difficult for the tip 116 to move up and down, and the tip 116 once lowered may not return to the initial state. Therefore, in the present embodiment, when the contact portion 114 starts to descend slightly due to the pressing contact of the contact object, the contact pressure of the front end portion 116 against the front wall portion 110 is increased by the elastic action of the leaf spring portion 112a and the contact portion 114.
  • the contact pressure with the inner surface of the front wall portion 110 is set to a predetermined contact pressure by causing the inner surface of the inclined portion 110a to protrude inward from the inner surface of the front wall portion 110. Therefore, in the state of FIG. 17, when the pressing state by the contact object is released, the tip end portion 116 is compatible with the restoring force of the leaf spring portion 112a and the force in the returning direction due to the inclination of the inclined portion 110a even if the contact pressure is large. As a result, it can move upward with a low contact pressure and return to the state of FIG. 16 where the contact pressure is low.
