Abstract: A power tool includes a brake assembly including a swing member swingable about a pivot at an axial center decentered from a center of a brake member, a press member held by the swing member to come in contact with the brake member in response to the swing member swinging, and a spring having an axial center at a second decentered position opposite to the pivot with the center of the brake member between the axial center and the pivot. The axial center is on a second line orthogonal to a first line extending through the center of the brake member and the pivot. The spring has an elastic movable end in contact with an end of the swing member to urge the swing member to a position at which the press member is in contact with the brake member with a switch being in an off state.

Abstract: A reciprocating tool includes a motor, a motion converting mechanism, a body housing, an inner housing, a support body, and a counterweight. The motion converting mechanism is operably coupled to a motor shaft and is configured to convert rotation into a linear reciprocating motion along a driving axis. The inner housing is within the body housing and houses at least a portion of the motion converting mechanism. The support body is originally separate from the inner housing and is attached to the inner housing in the body housing. The counterweight is operably coupled to the motion converting mechanism and is configured to be driven by the motion converting mechanism. The counterweight is supported by the support body to be pivotable around a pivot axis that extends in a direction orthogonal to the driving axis. At least a portion of the counterweight is housed in the inner housing.

Abstract: A driving tool includes a driver configured to linearly move forward along a driving line to thereby strike and drive a fastener into a workpiece. The driver includes a striking member, a support member, and an engagement member engaged with the striking member and the support member and configured to restrict movement of the striking member relative to the support member in a front-rear direction. The support member includes a support surface supporting a portion of the striking member, at least one receiving surface configured to receive a reaction force to the striking member caused by driving of the fastener, and restricting parts spaced apart from each other in the front-rear direction, located at an opposite side of the striking member from the support surface in a crossing direction crossing the support surface, and configured to restrict movement of the striking member in a direction away from the support surface.

Abstract: A portable power tool includes a tool accessory, drive mechanism, housing and grip having a rotating axis. The grip includes grip portion having a first face and a second face. The grip portion is formed in a rotation asymmetric shape to the rotating axis. The grip is attachable to the housing with respect to a rotating angle around the rotating axis at a first angle and a second angle. When the grip is viewed in the rotating axis extending direction, the position of the first surface and the position of the second surface in the circumferential direction around the rotating axis in a case that the rotating angle is at the first angle are different from the position of the first surface and the position of the second surface in the circumferential direction around the rotating axis in a case that the rotating angle is at the second angle.

Abstract: A power tool includes a housing formed of two half-housings and an end cap. A stator is mounted in the housing, and a rotor including a rotor core and a permanent magnet is mounted in the stator core. A rotary shaft having an axis of rotation extending in a front-rear direction supports the rotor core. Insulators are mounted at front and rear axial ends of the stator core, a planetary gear is mounted forward of the rotor core and a handle extends from the housing. The front insulator includes two recesses, and a first portion of each recess opens radially and a second portion of each recess opens axially rearward. Portions of the stator core cover the recesses, and projections extend from the housing and respectively mate with the recesses.

Abstract: A light unit is less likely to have lower light emission performance upon receiving a shock. An electric work machine includes a motor, a housing including a motor compartment accommodating the motor and a grip protruding downward from the motor compartment, an output unit located frontward from the motor and operable with a rotational force from the motor, a substrate extending above, on a left, and on a right of the output unit, and a plurality of light emitters mounted on a front surface of the substrate at intervals in a circumferential direction of the output unit. A light emitter of the plurality of light emitters nearest an apex of the substrate immediately above the output unit is at a position shifted circumferentially by a predetermined angle from the apex.
