Power tool

A power tool configured to oscillatory drive one of plural kinds of tool accessories selectively mounted thereto, the power tool comprising:

• a brushless motor having an output shaft, the output shaft being rotatable around a first axis;
• a spindle configured to removably receive a tool accessory and rotatably supported around a second axis, the second axis extending in parallel to the first axis;
• a transmitting mechanism configured to transmit rotation of the output shaft to the spindle and reciprocally rotate the spindle within a specified angle range around the second axis;
• an elongate support body having a longitudinal axis and supporting the brushless motor, the spindle and the transmitting mechanism;
• an elongate housing that houses the support body;
• and
• an elastic member interposed between the housing and a first end part of the support body and connecting the housing and the support body so as to be movable relative to each other, the first end part forming an end part of the support body in a direction of the longitudinal axis, wherein:
• the brushless motor, the spindle and the transmitting mechanism are supported in the first end part such that the first axis and the second axis cross the direction of the longitudinal axis,
• an inertia moment of the support body around the second axis, the support body supporting the brushless motor, the spindle and the transmitting mechanism, is at least 20 times of an inertia moment of a tool accessory around the second axis, when the tool accessory having a largest mass among the plural kinds of the tool accessories is mounted to the spindle.
