Document Type and Number:
Japanese Patent JP4643298
Kind Code:
B2
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. A second engagement member is formed on an inner face of the recess and engaging with the first engagement member so as 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.
