Abstract: A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

Abstract: A power tool includes a hammer mechanism, a brushless motor and a cooling fan. The brushless motor includes a rotary member having a motor shaft operably coupled to the hammer mechanism for linearly driving a tool accessory. The cooling fan has a first blade part and is configured to be rotated by the rotary member. The cooling fan includes a polymer portion, which forms at least a portion of the first blade part, and a metal portion disposed in or on the polymer portion. When viewed in a direction parallel to a rotational axis of the cooling fan, the metal member at least partially overlaps the first blade part in a radial direction of the cooling fan.

Abstract: A reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.

Abstract: A dust collecting system includes a power tool and a dust collector, The dust collector includes a body, a sliding part, a biasing member, a lock member and an actuator. The body is configured to be removably attached to the power tool. The sliding part is held by the body so as to be slidable along a sliding axis. The biasing member is configured to bias the sliding part forward to hold the sliding part in a first position. The lock member is configured to lock the sliding part relative to the body in a second position. The actuator is configured to unlock the sliding part locked by the lock member, by operating in response to a motor-starting operation for the power tool by a user.
