Abstract: A work tool includes a spindle, a clamp shaft, a holding member, an engagement member and a first biasing member. The holding member has a pass-through part. The engagement member is rotatable around a driving axis relative to the holding member between a first position in which the engagement member is allowed to pass through the pass-through part and a second position in which the engagement member is engaged with the holding member. The engagement member allows the clamp shaft to move in an up-down direction relative to the holding member when located in the first position, and to prevent the clamp shaft from moving downward relative to the holding member when located in the second position. The holding member is configured to fixedly hold the clamp shaft relative to the spindle while being biased upward by the first biasing member, with the engagement member in the second position.

Abstract: A power tool includes a motor, a spindle, an inner housing, an outer housing formed by an upper member and a lower member, a pair of interposing members and a pair of elastic members. The interposing members are arranged leftward and rightward of the inner housing, respectively, and fixedly connected to a first member, which is one of the upper member and the lower member, and at least partially in contact with an inner surface of the first member. The elastic members are held between a left portion of the inner housing and one of the interposing members and between a right portion of the inner housing and the other of the interposing members, respectively. A first end portion of each of the interposing members has at least one first surface extending to be closer to the inner housing toward a tip end of the first end portion.

Abstract: A work tool includes a spindle, a clamp shaft and at least one biasing part. The spindle is configured to be reciprocally rotated within a specified angle range around a driving axis. The spindle has a first inclined face inclined in a direction crossing the driving axis. The clamp shaft includes a shaft part and a head part. The shaft part is configured to be coaxially inserted into the spindle. The head part is formed on a lower end portion of the shaft part and configured to clamp the tool accessory in cooperation with the spindle while a second inclined face of the tool accessory is pressed against the first inclined face. The at least one biasing part is provided in the spindle and configured to always bias the tool accessory downward while the tool accessory is clamped by the head part and the spindle.

Abstract: Several means 71, 72, 73, 74, and 75 are provided for restricting a relative displacement in a separating direction of half-split housings 50L, 50R. At one or more of several screw-connection parts 60 of the left and right half-split housings 50L, 50R, a press-fitting protrusion 71a is provided in an insertion hole 62a of a boss-receiving part 62 into which a screw-boss part 61 is inserted. By press-fitting the screw-boss part 61 to the boss-receiving part 62, a separation resistance may be introduced between the left and right half-split housings 50L, 50R.

Abstract: An electric tool, such as an angle driver, has a main tool body with a front portion and a rear portion positioned opposite to the front portion. The main tool body houses a motor configured to receive electricity to function as a drive source. A gear head is coupled with the front portion of the main tool body wherein the gear head has a spindle in communication with a motor axis of the motor via mesh-engagement of bevel gears associated with the motor axis. The spindle has with a cutter tool accessory attached thereto such that rotation of the motor axis produces a commensurate rotation of the cutter tool accessory. Battery attachment portions are associated with the rear portion of the main tool body and are configured to receive a corresponding set of batteries that provide electricity to power the motor.
