造からなる振動発生装置。[Scope of claim for utility model registration] A fixed ratchet fixed inside the outer frame of the tool body, a rotating ratchet fixed to the output shaft,
A drill chuck fixed to the tip of the output shaft and a drill bit held by the drill chuck are provided, and the rotation of the motor is transmitted at a reduced speed to rotate the output shaft and the tool body is pressed against the fixed ratchet and the rotating ratchet. In a vibration drill used for drilling work by applying rotation and slight reciprocating motion to a drill bit, the fixed ratchet is integrally formed on the bottom surface of a cylindrical bearing holding sleeve, and the bearing holding sleeve is formed of plastic. The bearing holding sleeve is inserted into the tool side opening of the outer frame body, and a ring having a sealing member arranged on the inner diameter part is screwed into the opening via a bearing that pivotally supports the output shaft. A vibration generator with a structure that is fixed to the opening so that it does not come off.
