That is, the moving plate 201 moves back and forth to amplify the vibration, thereby maximizing the massage effect.

The elastic deformation member 270 is a component for positioning the moving plate 201 inside the open hole, and can be made of a material such as rubber so that the original shape can be restored by its own elastic force after elastic deformation. For example, when the moving plate 201 moves in the front-back direction, the elastic deformation member 270 repeats the action of extending or shortening its length in the front-back direction, thereby improving the repulsive force.

The elastic member 700 may have a coil spring shape to apply a compressive elastic force in the forward and backward directions, and the rear end of the elastic member 700 is fixedly supported in the installation space 210 to apply a compressive elastic force forward. .

The lower locking groove 250 may have a shape that is horizontally recessed from the front of the head 200 and then recessed downward, and when the contact pad 800 is coupled to the front of the head 200, the upper protrusion (850) may be in close contact with the top of the head portion 200.

For example, the lower protrusion 840 can be inserted into the lower locking groove 250 while pushing the lower end of the first locking end 841 toward the front of the lower locking groove 250. In this state, when the upper end of the contact pad 800 is rotated backward and brought into close contact with the front of the head 200, the upper protrusion 850 comes into close contact with the upper surface of the head 200 and the second stopping end 851 ) can be inserted into the upper locking groove 260.
