PROBLEM TO BE SOLVED: To provide a technique contributing to suppression of vibration generated when rotating a motor in a power tool. SOLUTION: This power tool has a tool body 103, a distal end tool 119 arranged in a distal end region of the tool body 103, a grip 109 connected on the opposite side of the distal end tool 119 of the tool body 103, the motor 111 stored in the tool body 103 to drive the distal end tool 119, bearings 151 and 153 on the distal end tool side and the grip side to rotatably support a rotary shaft of the motor 111, a distal end tool side bearing storing part 152 for storing the bearing on the distal end tool side, a grip side bearing storing part 157 provided in an extended state in the axial direction of the motor 111 from the grip side end part of the tool body 103 toward the grip side to store the bearing on the grip side, and a ring-shaped member 159 arranged in a loosely fitting state on an outer periphery of the grip side bearing storing part 157. The grip 109 has a cover region 163a for covering the grip side bearing storing part 157 and supports the extended end part region of the grip side bearing storing part 157 via an elastic body 167 in the cover region 163a.
