摘要： PROBLEM TO BE SOLVED: To contrive compactness by contriving an installation place for a rotation preventing means for a lace at a movable side. SOLUTION: This eccentric thrust bearing 10 is interposed between a swirl member 3 having eccentric swirl motion and a fixed member 5 axially facing the swirl member 3. Where, a spindle and a circular recessed part are separately provided to inhibit the rotation of the swirl member 3 and that of the lace at the movable side on the circumference of the lace at the movable side and that of a lace at a fixed side. Unlike conventional methods, this eliminates the need for uselessly increasing the outside dimension of the swirl member 3 and that of the lace at the movable side.

摘要： PROBLEM TO BE SOLVED: To certainly prevent burning seizure at the time of starting-up. SOLUTION: When this planetary transmission mechanism and a pump stop, a centrifugal force generated in operation and a feed pressure P1 by the pump as shown in Figure (a) are eliminated as shown in Figure (b). In a support shaft 7 located above a shaft center C, a valve element 21 falls by its own weight and abuts on a valve seat 20 to close a valve 19. Thereby, the fall and outflow of a lubricant from an upper lubricant reservoir 14 through a lower introduction passage 16 can be prevented, so that the lubricant can be retained in the lubricant reservoir 14.

摘要： PURPOSE: To improve the root strength and lubricity of a column part by a method wherein two sides positioned back to back are formed in parallel to each other at a column part between adjoining pockets, and a protrusion part protruded to the pocket side is formed on a region on the outside diameter side. CONSTITUTION: Pockets 11 to contain respective needle-form rollers 9 are arranged at a plurality of spots on the periphery of a cage 10. A column part 13 between the adjoining pockets 11 having two sides (S) positioned back to back and set in parallel or approximately in parallel to each other. Further, protrusion parts 14 protruded toward the central side of the pocket 11 are formed on respective regions situated in the intermediate position in an axial direction of each column part 13 and closer to the outside diameter side than a central part in a radial direction. This constitution prevents pull-off protection of the needle- form roller 9 to the inner and outer diameter sides and a strength at the inner peripheral portion of the column part 13 is improved. Further, in the cage 10, a separation part where two each of protrusion parts 16 and the protrusion parts 14 formed on the side wall surfaces of the respective column parts 13 are axially separated away from each other forms reversely a recessed part, and the recessed part ensures excellent lubricity of the needle-form rollers 9 in the pocket 11.
