ラツチ機構付電気ドリル。 In an electric drill that transmits the rotation of the motor to the spindle of the final shaft and performs drilling by attaching a tool to the tip of the spindle, there is a spindle clutch part having a large number of convex clutch pawls, and a part near the spindle clutch part. A gear clutch portion is provided on the rotation shaft of the spindle, which has a formed rotating shaft locking portion, a stepped bearing portion that supports a bearing, and a threaded portion on the tip side, so as to engage with the spindle clutch portion and rotate together with the spindle clutch portion. A spindle assembly comprising a gear and a compression spring positioned by a sleeve fixed to the stepped bearing part and loosely fitted with a compression spring that applies a predetermined biasing force to the gear. , attach it to the gear cover from the motor side, then screw the special nut to the threaded part while fixing the rotating shaft locking part of the spindle, and connect the bearing that rotationally supports the spindle with the sleeve. An electric drill with a slip clutch mechanism configured to be held in place by the
