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.
Claims14
A work tool configured to perform an operation on a workpiece by driving a tool accessory, the work tool comprising:
- a motor having an output shaft, the output shaft being rotatable around a first axis;
- a spindle having a tool mounting part and configured to reciprocally rotate within a prescribed angle range around a second axis by power of the motor and thereby oscillate the tool accessory mounted to the tool mounting part within an oscillation plane, the tool mounting part being configured such that the tool accessory is removably mounted thereto, the second axis being parallel to the first axis, the oscillation plane being orthogonal to the second axis;
- and
- an elongate housing in which the motor and the spindle are housed, wherein:
- when a longitudinal direction of the housing is defined as a front-rear direction, the housing includes:
- a front housing part in which at least the spindle is housed;
- and
- a rear housing part connected to a rear end portion of the front housing part and extending rearward,
- the front housing part includes a first contact part, the first contact part having at least one first contact surface, the at least one first contact surface extending in a direction crossing the oscillation plane,
- the rear housing part includes a second contact part, the second contact part having at least one second contact surface, the at least one second contact surface extending in the direction crossing the oscillation plane, and
- the first and second contact parts are connected together in a state in which the at least one first contact surface and the at least one second contact surface are held in contact with each other.
