摘要： A work tool includes a housing, a spindle, a clamp shaft, a biasing member, an operation member, a motion-converting mechanism and a pushing-down member. The spindle is supported to be rotatable around a driving axis. The clamp shaft is movable in the up-down direction relative to the spindle. The biasing member is configured to bias the clamp shaft upward relative to the spindle so as to apply to the clamp shaft a clamping force for clamping a tool accessory between a head part of the clamp shaft and a lower end portion of the spindle. The motion-converting mechanism is configured to move the pushing-down member in the up-down direction along with turning of the operation member around the driving axis. The pushing-down member is configured to be moved downward so as to push the tool accessory downward when the operation member is turned in a first direction.

摘要： 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.

摘要： 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.
