| PROBLEM TO BE SOLVED: To provide an oil pulse rotary tool suppressed in elongation of the total length even when providing a coil spring.SOLUTION: A sleeve body 63 with bearings 65, 66 interposed between the sleeve body 63 and the center shaft 44 of an output part 41 is integrally coupled to an oil pulse generator 60. A coupling body 70 rotatable together with the output portion and movable in the axial direction X is externally attached to the sleeve body, and balls 80, 80 are straddlingly fitted between an outer surface of the sleeve body and an inner surface of the coupling body. Cam grooves 68, 68 tilted from the axial direction of the sleeve body are formed at a fitted portion of the ball on the outer surface of the sleeve body, and the coil spring 85 energizing the coupling body to a retreated position P is provided to the oil pulse generator in an externally attached state. The rotation of the output part is transmitted to the sleeve body and oil pulse generator from the coupling body via the balls, and when a difference is caused in the rotation speed between the sleeve body and coupling body, the coupling body is made to advance resisting against the energizing force of the coil spring by the relative movement in the cam grooves of the balls to relax an impact. | ||||||
