摘要： A hammering tool includes, within its tool main body, a piston which reciprocates by using a motor as its drive force, a hammering member which carries out its hammering operation in linking with the reciprocating motion of the piston, and an intermediate member which transmits a hammering force of the hammering member to a top end tool mounted on the top end of the tool main body. The tool main body further includes a measuring device which measures a hammering state of the hammering member and a control device which controls the number of rotations of the motor. The control device, according to measurement results of the measuring device, determines the limit number of times of hammering where the hammering member becomes unable to follow the reciprocating motion of the piston, and thus controls the number of rotations of the motor.

摘要： An intermediate shaft 3 operatively coupled to a motor and a tool holding sleeve 11 for holding a tip end tool 22 are disposed in a housing 1 in parallel with each other. A motion converting member 5 for converting rotary motion to reciprocating motion thereby to operate the tip end tool 22 to hammer is rotatably provided on the intermediate shaft 3. A first clutch 6 is provided between the intermediate shaft 3 and the motion converting member 5. A clutch sleeve 25 which is coupled to the intermediate shaft 3 by way of a rotation transmitting member, and a second clutch 27 which rotates integrally with the tool holding sleeve 11 and can move in a longitudinal direction of the tool holding sleeve are arranged on an outer periphery of the tool holding sleeve 11. The second clutch 27 is provided so as to be engaged with and disengaged from the clutch sleeve 25.

摘要： In a driving tool, a diameter of an intermediate member is enlarged to increase a mass of the intermediate member and an outside diameter of a cylinder at a position where the intermediate member is internally provided is enlarged in accordance with the enlarged diameter of the intermediate member. Further, in the driving tool, a bearing thickness of a ball bearing is reduced correspondingly to a dimension of the enlarged outside diameter of the cylinder and a washer is provided at a part where the ball bearing abuts on the cylinder in the forward and backward moving direction thereof.
