摘要： To provide a cam clutch unit that is easy to handle before assembly, with its components prevented from lifting or detachment, and that allows production with fewer machining steps and a lower level of difficulty, while also enabling unit thickness reduction. The cam clutch unit of the present invention includes: a plurality of cams arranged between an inner race and an outer race; a cage ring having a plurality of pocket portions that restrict relative circumferential movements of the cams; and an annular spring that biases the cams. The cams have an engagement step adapted to engage with the spring on one axial end face. The cage ring has a plurality of hook portions that restrict an axial movement of the annular spring. The hook portions have a pressing part that allows the spring to press the cams towards the other axial end.

摘要： To provide a simple-structured chain guide assembly frame capable of reliably maintaining a correct positional relationship between a driven sprocket and a sprocket holding portion without the possibility of driven sprocket detachment. The chain guide assembly frame includes a main body having a fixed-guide-side sprocket holding portion and a pivoting-guide-side sprocket holding portion. The fixed-guide-side sprocket holding portion includes a first fixed-guide-side support portion that supports a driven sprocket at a first contact point, and a second fixed-guide-side support portion that supports the driven sprocket at a second contact point located more outside than the first contact point. When the driven sprocket is in an erected state in which the driven sprocket is supported at the first contact point and second contact point, the vector of gravity acting on the gravity center of the driven sprocket points between the first contact point and second contact point.

摘要： An object of the present invention is to provide a chain that is easy to assemble, has a longer life and smaller size, and allows larger tolerance for misalignment. The object is achieved by a chain including a plurality of outer links each having a pair of outer plates and pins, and a plurality of inner links each having a pair of inner plates and bushings, alternately and pivotably coupled together in the longitudinal direction of the chain by the pins rotatably inserted into the bushings, with a position restricting part positioned between each pair of the inner plates to restrict inward movement of each pair of inner plates in the chain width direction. The bushings are rotatably inserted in respective bushing holes of each pair of inner plates.
