Abstract: An electric oscillating tool has an electric motor having an output shaft, an eccentric shaft that is connected to one end region of the output shaft, and a weight that is connected to the other end region of the output shaft. A blade as a tool accessory is driven to reciprocally rotate around a spindle by reciprocating motion of the eccentric shaft in a transverse direction of the electric oscillating tool. The weight is driven to cancel out the inertial force of the eccentric shaft, so that the output shaft is stably rotated.

Abstract: A power tool, such as an oscillating multi-tool, is configured to drive a tool accessory in an oscillating manner. The power tool includes a motor, and a spindle supported to be rotatable around a driving axis and configured to pivotally oscillate the tool accessory, which is removably mounted on the spindle, using power generated by the motor. An inner housing of the power tool houses the motor and the spindle, and has at least one airflow inlet and at least one airflow outlet. An outer housing of the power tool houses the inner housing and is elastically connected to the inner housing via at least one elastic member to be movable relative to the inner housing. A partition is disposed between the at least one inlet and the at least one outlet. The partition divides a space defined between the inner and outer housings into first and second airflow spaces.

Abstract: A work tool includes a housing, a spindle, a motor a transmitting mechanism, and a heat dissipation part. The transmitting mechanism is configured to transmit rotation of a first shaft of the motor to the spindle to cause the spindle to rotary oscillate. The transmitting mechanism includes a metal second shaft coupled to the first shaft and having an eccentric part, a drive bearing including an inner ring fixed around the eccentric part, an outer ring, a plastic retainer arranged between the inner ring and the outer ring, and rolling elements rollably retained by the retainer, and an oscillating member having a first end portion fixed to the spindle and a second end portion abutting on an outer periphery of the outer ring. The heat dissipation part is made of metal, arranged in contact with the second shaft and configured to rotate integrally with the second shaft.

Abstract: A work tool includes an an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: A power tool includes a motor, a switch, a housing, a switching member and a holding member. The housing is a hollow body formed by a first housing part and a second housing part connected with the first housing part. The first housing part has a through hole. The switching member is connected to the switch and includes an operation part exposed outside through the through hole so as to be movable in a specified direction in response to a user's manual operation. The switching member is configured to turn the switch on and off by linearly moving in the specified direction. The holding member is supported by at least one of the first housing part and the second housing part within the housing and configured to hold the switching member between the holding member and the first housing part so as to be linearly movable in the specified direction.
