Abstract: A rotary hammer includes a tool body, a tool holder, a cylinder, and a coupling member. The tool holder has a tubular shape and a longitudinal axis. The tool holder is configured to hold a tool accessory to be movable along the longitudinal axis and is supported by the tool body to be rotatable around the longitudinal axis. The cylinder extends coaxially with the tool holder and is supported by the tool body to be rotatable around the longitudinal axis. The coupling member is between the tool holder and the cylinder in a radial direction of the tool holder and is engaged with the tool holder and the cylinder to couple the tool holder and the cylinder together such that the tool holder and the cylinder integrally rotate.

Abstract: An electric work machine, such as a lawn mower includes a motor case (22) fixed inside a main-body housing (10). A brushless motor (21) is housed inside the motor case (22) and includes a stator (23) having a stator core (40), coils (45), and upper and lower insulators (42, 43), and a rotor (24) disposed inward of the stator (23) and having a rotary shaft (25). A spindle (17) is driven by the rotary shaft (25). The motor case (22) holds the stator (23) and axially supports the rotary shaft (25) via bearings (68, 76). One or more insulating members, such as an insulating cap (67) and/or a resin layer (78), provide electrical insulation between the stator core (40) and the rotary shaft (25).

Abstract: A power tool having a hammer mechanism has a tool body that houses a motor and a driving mechanism and extends in a front-rear direction; a handle including a grip part that extends in an up-down direction orthogonal to the front-rear direction behind the tool body and has a lower end formed as a free end and is arranged below the driving axis; and a plurality of biasing members configured to elastically connect the tool body and the handle. The biasing members include at least one first biasing member arranged above the driving axis in the up-down direction, and at least one second biasing member arranged below the driving axis in the up-down direction. In this power tool, a biasing force of the at least one second biasing member is larger than a biasing force of the at least one first biasing member.

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.
