<p>In a hydraulic continuous variable transmission device (1) which is a movable swash plate type hydraulic device, an annular groove (10f) is formed on at least one of a front surface (12a) of a thrust plate (12) and a facing surface (10d2) of a movable swash plate (10) adjoining the front surface (12a), and the annular groove (10f) is used as a lubricated flow path (28). An eject flow path (10c) is provided on the movable swash plate (10). The eject flow path (10c) is linked with a rear surface (13b), that is, a sliding surface of a half bearing (13) which brings the lubricated flow path (28) to slidingly touch the movable swash plate (10). An ingress flow path (12c) is provided on the thrust plate (12). The ingress flow path (12c) links a supply flow path (8b) inside a plunger shoe (8a) of a plunger, located at a high pressure range (H), with the lubricated flow path (28).</p> |
