効果がある。Since the nozzle portion 12c is inserted in the concave portion 9a at a constant interval in the vertical direction and the horizontal direction, this combination has a stopper action for limiting the elastic deformation of the elastic body 9 to a predetermined amount. . Therefore, it is possible to prevent the elastic body 9 from being excessively elastically deformed and damaged. When the above stopper action is exerted, the nozzle portion 12c made of sheet metal comes into contact with the elastic body 9 made of a rubber-like elastic material instead of the rigid component, so that the contact is soft and there is a buffering effect.
