PROBLEM TO BE SOLVED: To provide a torque tool capable of changing a racing angle in the present invention.SOLUTION: A torque tool of the present invention is provided with a hollow head, a gear part for rotating in the head and a plurality of meshing kits installed in the head. The respective meshing kits reciprocate between a meshing position and a separation position. The meshing kits mesh with any one gear of the gear part by selecting a single mode or a replacement mode by a push rod arranged in the head. In the single mode, only one meshing kit is meshed with the gear part, and an angle of racing by surrounding the gear part by the head is equal to magnification of a sandwiching angle formed in adjacent two gears of the gear part. In the replacement mode, these meshing kits are meshed in order with the gear part, and the angle of racing by surrounding the gear part by the head is smaller than in the single mode, and the head of the torque tool is adapted to a narrow operation space.SELECTED DRAWING: Figure 3 |
