摘要： A screw driver capable of avoiding co-rotation of an end bit and a motor in case of sharp shooting the end bit with a groove in a head of a screw. A co-rotation preventing mechanism is engageable with an end bit mounting portion when the end bit mounting portion is at a frontward position to prevent the end bit mounting portion from being rotated in the forward direction and to allow the end bit mounting portion to rotate in the reverse direction. The preventing mechanism is disengageable from the end bit mounting portion when the end bit mounting portion is at the rearward position to allow the end bit mounting portion to rotate in both forward and reverse directions.

The counterweight holding member (73) extends in a direction perpendicular to directions of the reciprocation motion and is capable of being elastically deformed in the directions of the reciprocation motion. The counterweight (74) is supported by the counterweight holding member (73) and is capable of reciprocating in the directions of reciprocation motion together with the counterweight holding member (73). The support members (71,72) are positioned away from the counterweight (74) by a predetermined distance for supporting the counterweight holding member (73) to the housing (10,20,30). The counterweight (74) is interposed between or among the support members (71,72).

摘要： An elastic unit includes a transatory unit including a first elastic support member, a second elastic support member and not-shown four round bar-shaped elastic bodies made of rubber. A rotation urging unit is composed of a Neidhart spring including an outer frame, a shaft, a rotary member, and four rubber rods. The rotary member is in a state where it is rotated at 10° counterclockwise from an initial state. Therefore, the rubber rod deforms upon reception of rolling friction from the outer frame and the rotary member, and the rotation urging unit gives the handle portion the urging power by which the handle portion is rotated so that one end of the handle portion is spaced away from a gear housing 31 in the direction of the handle portion.
