    摘要： A needle roller bearing comprises an outer ring having a plurality of outer ring members split by a parting line extending in the axial direction of the bearing, and a plurality of needle rollers rotatably arranged on the raceway surface of the outer ring. Thus, a non-contact length “L” between the outer ring members and the needle roller at an abutment part of the adjacent outer ring members, and an effective length “w” of the needle roller has a relation such that L/w

    摘要： A valve-operating system for an internal combustion engine includes cam followers which have cam abutment portions abutting against valve-operating cams provided on a camshaft and which are swingably carried in an engine body and operatively connected to engine valves biased in a closing direction by a valve spring. The cam followers are biased in a direction of abutment of the cam abutment portions against the valve-operating cams by a resilient biasing means different from the valve spring. A resilient biasing means includes a pull rod connected at one end thereof to the cam follower, and a compression coil spring interposed between the other end of the pull rod and the engine body to pull the pull rod to bias the cam follower in a direction of abutment of the cam abutment portion against the valve-operating cam. Thus, the resilient biasing means is constructed to be compact, leading to an increase in degree of freedom of the design of the structure of the valve-operating system.
