    • In the inner and outer surfaces of the retainer 34b, there are formed recessed grooves 40a, 40a which serve as lubricating oil flow passages for allowing lubricating oil to flow into pockets. Where the axial-direction depth of the recessed groove 40a, 40a is expressed as H and the circumferential-direction width thereof is expressed as 2L, 0.20≦H/L≦0.97 can be satisfied. Accordingly, it is possible to provide a toroidal-type continuously variable transmission which can prevent the damage of a retainer 34b incorporated into a thrust rolling bearing for supporting a power roller and also can enhance the lubricating efficiency of the present thrust rolling bearing.
    • 在保持器34b的内表面和外表面上形成有用于允许润滑油流入袋中的润滑油流动通道的凹槽40a,40a。 在凹槽40a,40a的轴向深度表示为H,其周向宽度被表示为2L的情况下,可以满足0.20 <= H / L <= 0.97。 因此,可以提供一种能够防止结合在用于支撑动力辊的推力滚动轴承中的保持器34b的损坏的环形无级变速器,并且还可以提高本推力滚动轴承的润滑效率。

    • A comb-shaped cage for use in a roller bearing having one circular portion axially opposed to the end surface of each of rollers and a plurality of bar portions protruding from one or both axial sides of the circular portion and arranged circumferentially opposed to the rolling surface of each rollers is disclosed. It is designed so as to satisfy the condition 0.2≦(I1′/I3′)≦2.5, wherein I1′ expresses the moment of inertia of area for the circular portion relative to a neutral axis parallel with the longitudinal direction of the bar portion and I3′ expresses the moment of inertia of area for the bar portion relative to a neutral axis parallel with the circumferential direction of the cage. This enables to improve the strength of the cage without lowering the load capacity of the bearing to which the cage is assembled.

    • A cage for use in a roller bearing having a plurality of bar portions arranged circumferentially and a pair of circular portions connecting both axial ends of the plurality of bar portions. A circular portion having a larger or equal diameter, in the pair of the circular portions, is referred to as a circular portion, the other of them is referred to as a second circular portion, and it is designed to provide, for example, such a relation as: 0.8≦(I1/I2)≦1.4, and 0.1≦(I1/I3)≦3.0 in which the moment of inertia of area for the circular portion is I1, the moment of inertia of area for the second circular portion is I2, and the moment of inertia of area for the bar portion 7 is I3. This enables to improve the strength of the cage without lowering the load capacity of the bearing to which the cage is assembled.

    • A wobble plate type refrigerant compressor is disclosed which includes a compressor housing having a crank chamber and a cylinder block which is provided with an axial central bore and a plurality of cylinders. A plurality of pistons are slidably fitted within each of the cylinders. A wedge-shaped cam rotor is disposed within the crank chamber to rotate together with a drive shaft. A wobble plate is coupled to the pistons through each corresponding connecting rod. The wobble plate is disposed on the inclined surface of the cam rotor to convert rotating motion of the cam rotor into reciprocating motion to be imparted to the pistons while preventing the rotating motion of the wobble plate. A first bevel gear is fixed on the wobble plate and a second bevel gear connected thereto is supported by the cylinder block. The second bevel gear includes a shank portion which is non-rotatably disposed within the central bore of the cylinder block by means of at least one engaging mechanism, such as a key/groove mechanism, provided between the second bevel gear and the cylinder block. The first and second bevel gears intermesh through spherical member to prevent rotation of the wobble plate. The engaging mechanism includes an axial hollow space or groove formed between the shank portion of the second bevel gear and the cylinder block, and a rod member or key fittingly disposed within the axial hollow space. The engaging mechanism further includes a dampening member or vibroisolating member for dampening torque which acts on the shank portion of the second bevel gear to thereby reduce vibration and noise.
