Abstract: An impact tool includes a motor, a hammer casing with an opened rear end and a disk-shaped member coupled to the hammer casing to close the opened rear end and to rotatably support a spindle. A first engagement member is formed on an outer face of the disk-shaped member. A second engagement member is formed on an inner face of the recess and engaging with the first engagement member to restrict a movement of the hammer casing in a second direction parallel to a rotation axis of the spindle. A third engagement member is formed on an outer face of the hammer casing. A fourth engagement member is formed on an inner face of the housing body and engaging with the third engagement member so as to restrict a movement of the hammer casing in the first direction.

Abstract: A battery-operated electric power tool (1) includes a light unit (11) disposed on the front end of the main housing (2) and extending along the underside of the gear housing (6). The light unit (11) includes a light source (12) in a casing with the light emitting end of the light source (12) exposed through a hole at the front of the unit (11). The electric power tool (1) further includes at the front portion of the gear housing (6) a bumper (13) made of a molded rubber containing selfiuminous pigment. While the electric power tool (1) is operated with the light source (12) on, the bumper (13) absorbs and stores part of the light from the light source (12) and emits light therefrom, enabling the user to locate the bumper (13) in darkness or a dimly lit work environment even after sustained use in darkness.

Abstract: A housing body has a recess. A motor is housed in the housing body at a rear side of the recess. A hammer casing houses a rotatable spindle and an impact mechanism operable to convert the rotation of the spindle into intermittent impact actions in a first direction which is a circumferential direction of the spindle, and has an opened rear end. The hammer casing is mounted in the recess. A disk-shaped member is coupled to the hammer casing so as to close the opened rear end and to rotatably support the spindle. The disk-shaped member has a through hole receiving an output axis of the motor, thereby causing the output axis of the motor to couple with the spindle to transmit a rotation of the motor to rotate the spindle. A first engagement member is formed on an outer face of the disk-shaped member.

Abstract: A battery-operated impact driver (1) includes a light unit (11) disposed on the front end of the main housing (2) and extending along the underside of the gear housing (6). The light unit (11) includes a light source (12) in a casing with the light emitting end of the light source (12) exposed through a hole at the front of the unit (11). The impact driver (1) further includes at the front portion of the gear housing (6) a bumper (13) made of a molded rubber containing selfluminous pigment. While the impact driver (1) is operated with the light source (12) on, the bumper (13) absorbs and stores part of the light from the light source (12) and emits light therefrom, enabling the user to locate the bumper (13) in darkness or a dimly lit work environment even after sustained use in darkness.
