Abstract
An electric power tool includes a housing, a motor, a deceleration mechanism, a final output shaft, a vibration mechanism, a vibration switching member, a stop member, and an expansion prevention portion. The vibration mechanism provides a vibration in an axial direction to the final output shaft. The vibration switching member is accommodated in a slit axially disposed on a front end of a tubular portion and moved back and forth in the slit by an operation from outside to switch on and off actuation of the vibration mechanism. The stop member is installed on the front end of the tubular portion to cover the slit. The expansion prevention portion is disposed on the stop member and is brought in contact with an outer periphery of the front end of the tubular portion to prevent the front end of the tubular portion from expanding,
