    Abstract: A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a first cylindrical portion (36) extending in a direction of a rotation axis (12); a first disc portion (31) continuous with the first cylindrical portion (36) and extending in a radially outward direction; and a second cylindrical portion (37) continuous with the first disc portion (31) and extending in the direction of the rotation axis (12). The first cylindrical portion (36), the first disc portion (31), and the second cylindrical portion (37) are formed in an area located radially inside the pockets (21). The height (H36) of the first cylindrical portion (36) in the direction of the rotation axis is smaller than the height (H37) of the second cylindrical portion (37) in the direction of the rotation axis.

    Abstract: A chain guide includes a guide base pivotable about a fulcrum shaft. The fulcrum shaft is arranged between a roller bearing located at the end portion of the guide base, which is closer to the fulcrum shaft, and the center of the guide base in the longitudinal direction of the guide base such that the roller is arranged outside of the fulcrum shaft. In this arrangement, since the rotation moment applied to the above roller bearing due to the pressing force from a chain acts to alleviate the rotation moment applied to the remaining roller bearings, the guise base is less likely to bend.

    Abstract: A chain transmission device for driving camshafts is provided, the device including a chain including a loose side chain portion, and trained around the crank sprocket and the cam sprockets, and a chain guide mounted on the outer side of the loose side chain portion so as to be pivotable about one of the two end portions of the chain guide, and provided with a plurality of rotatable rollers. An adjustment force is applied to the other of the two end portions of the chain guide by a chain tensioner such that the chain guide is biased toward the chain, so that the rollers of the chain guide can guide the chain by rolling. The winding angle of the portion of the chain located on the outer periphery of the roller located closest to the crank sprocket is set to be 170 degrees or over so as to reduce noise.
