<p>[PROBLEMS] To provide an adjusting tool which can set a clearance with high precision in a short time. [MEANS FOR SOLVING PROBLEMS] The nut portion (22) of an adjusting tool (20) is made to engage with an adjust screw (3) and then the adjust screw (3) is driven by rotating an output shaft (21) forwardly. When the output shaft (21) is rotated forward, driving force from an input shaft (23) is transmitted to a ratchet mechanism (25) with a one-way clutch (24a) off, a one-way clutch (24b) on, a one-way clutch (24c) off, and a one-way clutch (24d) on, as shown in Fig. 4(a), and then transmitted to the output shaft (21) through the ring gear (31) of a planetary gear mechanism (30) and a carrier. When the output shaft (21) is rotated reversely, driving force from the input shaft (23) is transmitted to the output shaft (21) through the sun gear (32) of the planetary gear mechanism (30) with the one-way clutch (24a) on and the one-way clutch (24c) off, as shown in Fig. 4(b).</p> |
