Abstract: An electric driver includes a hook portion which is constituted by a deformable hook-like portion and a connecting portion for connecting the hook-like portion to the handle. The hook-like portion is constituted by a base portion connected to the connecting portion and a bent portion continuous to the base portion, and a front end portion continuous to the bent portion and arranged at a position substantially opposed to the base portion. The front end portion and the base portion can be proximate to and remote from each other. The connecting portion holds the hook-like portion in a direction substantially the same as a direction in which the handle extends. The hook-like portion is pivotably held on a first rotating axis center extending in substantially the same direction as the handle.

Abstract: A wrenching portion provided in an adjuster and employed for assembling is formed at a gripping portion for rotation. The gripping portion is formed in a polygonal shape. In this configuration, the adjuster is decreased in size and weight and its operability of adjusting a driving depth is improved. An undercut portion is removed in a vertical direction and a non-slip rugged portion is provided in only a longitudinal direction so that it can be manufactured in a simple tow-part mold, thereby reducing the production cost.

The connecting portion holds the hook-like portion in a state of being hung down in a direction substantially the same as a direction of extending the handle. The hook-like portion is held centering on a first rotating axis center extended in the direction of hanging down the hook-like portion pivotably relative to the handle.

Abstract: A box nailing machine includes: a box nailing machine body having a nail driving port from which nails are driven; a handle portion having a handle arm; and a magazine for accommodating nails in it, the forward end portion of which is attached to the nail driving port, the portion of the magazine except for the forward end portion being attached to the handle portion via the handle arm. The magazine has a handle arm attaching portion for attaching the magazine to the handle arm. The magazine is made of metal and formed substantially U-shape by press forming. A washer is integrally formed in the handle arm attaching portion so that the washer is disposed between a head portion of a fixing bolt and the magazine.
