  • Publication number: 20240066678
    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.
