PURPOSE:To constituted a separator so that an operator holds it like a pencil holder and puts it on an outer crown, and can adjust it by a delicate touch by driving a cam ring by a motor shaft of a driving motor, and placing eccentrically the motor shaft and a hammer piece in a parallel state. CONSTITUTION:A separator by a light hitting type vibration method is used in the case of removing an outer 8 and an inner crown 9 from a temporarily attached state, etc., in a making stage of a prosthetic object. In the outer crown 8, an engaging projection 8a is constituted on the outside, and by allowing the tip of a hammer piece 1 to abut against the engaging projection 8a, vibration is given, and by the vibration, the part between the inner crown 9 and the outer crown 8 fitted by a tapered part is removed simply. Between a battery 5 and a driving motor M, a switch 7 is placed, a motor shaft 3 of the driving motor M is extended forward, and a cam ring 2 is fixed to the tip. The cam ring 2 is a little eccentric from the center of a hand piece case 4, and in a position of the center of the hand piece case 4, the hammer piece 1 is placed, and the hammer piece 1 and the motor shaft 3 are placed in parallel. |
