Abstract
A hydraulic intensifier generates a hydraulic pressure which is higher than the input hydraulic pressure generated in the discharge port and the outer periphery hydraulic pressure chamber. The hydraulic intensifier, provided inside a case member, has a discharge part connected with an outer periphery hydraulic pressure chamber. An input port supplies input hydraulic pressure from the exterior to an input oil chamber of hydraulic intensifier. Oil is filled in a sealed manner in outer periphery hydraulic pressure chamber.and discharge part. The hydraulic intensifier is driven by the input hydraulic pressure. The rod is locked by the elastic deformation of a thinned tube part of a sleeve body. A relatively small hydraulic locking device having a relatively high power is achieved. Furthermore, a relatively small hydraulic pressure source having reduced pressure is realized.
