貫通式のものがある。The screwdriver has a through-type screwdriver, in which the driver rod is fitted into a through hole formed in the grip so as to protrude outward from one end, and the shaft rod is press-fitted from the other end so as to come into contact with the driver rod. There is something.
ところがこの種のドライバーでは、軸杆を単に貫通孔に
圧入するのみでは、使用の際に軸杆がドライバー杆より
圧入方向とは反対方向に大きな力を受け、該軸杆及びド
ライバー杆が軸方向に簡単にガタ付くようになる。However, with this type of driver, if the shaft rod is simply press-fitted into the through hole, the shaft rod will receive a large force from the driver rod in the opposite direction to the press-fitting direction during use, and the shaft rod and driver rod will be forced to move in the axial direction. It becomes loose easily.

点にある。In view of the above-mentioned problems, the present invention has a simple structure that allows the shaft rod to be firmly and easily assembled.The present invention is characterized by a grip having a through hole, and one end of which is inserted into the through hole. In a through-type driver that includes a driver rod that is fitted in an outwardly protruding shape and a shaft rod that is press-fitted into a through hole from the other end and abuts the driver rod, the outer peripheral surface of the shaft rod has a radially outer surface. An axial locking piece is provided that protrudes in the direction, and a retaining portion that protrudes radially outward or circumferentially from the press-fitting direction is provided on the opposite side of the locking piece from the press-fitting direction of the shaft rod. The point is that
