<p>PURPOSE:To enhance durability, by dividing a static pressure pad, which supports the reaction force of a piston being provided to be arranged on a fixed side, into plural groups and providing a means, which changes a sectional area of the pad, or a means which changes a pressure supplied to the pad. CONSTITUTION:A chamber 13 of a bearing sleeve 8, supporting a shaft 6A, inserts a rod part 17 of a static pressure bearing pad 16 formed by a throttle part 14 and a pressure chamber 15. The static pressure bearing pad 16, which is provided in plural quantity in the peripheral direction of a bearing sleeve 8, changes a sectional area of the pad 16 or a pressure supplied to the pad 16. Consequently, a driving shaft, even if it is eccentrically formed, enables a pad shoe part to be prevented from its uneven wear and even a direct contact to be prevented in a driving disc sliding surface.</p> |
