To provide a hydraulic motor furnished with a means to hold each propelling member mechanically at a bearing/contacting surface where a hydraulic seal to hinder a propulsive fluid from penetration must be secured.
The hydraulic motor is equipped with the propelling member placed between a cam 3 associated with a shaft 2 and a reaction element 1b. The propelling member 10 consists of two elements 11 and 12, i.e. an internal and an external, which can be slidingly drawn out and inserted in the radial direction to/from each other and are furnished with ring-shaped bearing edges 11a and 12a held in the pressed condition to the mating contacting surfaces 1a and 3a of the reaction element 1b and the cam 3 by their respective resilient means 16, wherein the resilient means associated with the external element 11 of the propelling member is positioned outside of the element. The resilient means 16 associated with the internal element 12 is positioned inside of the propelling member 10, and placed in the radial direction between the internal elements 12 and the means 52 and 55 related for holding them mechanically.
