A power transmission chain () has links (), pins (), and interpieces (). The links () each have a front and a back insertion parts () through which the pins are inserted. The pins () and the interpieces () connect links () that are arranged side by side in the lateral direction of the chain such that the front insertion part () of one of the links () and the rear insertion part () of the other link () correspond to each other, and the connection is made such that that the links () are bendable in the longitudinal direction. The locus of a contact position of a pin () and an interpiece () is an involute of a circle. Two or more kinds of sets of a pin () and an interpiece () having different radii of base circles of involutes are formed, and these sets of a pin () and an interpiece () are randomly arranged.

A sensor device includes: a detected part D having a movable elementand a fixed elementcontacting each other in which a contact area of the both elements changes corresponding to an external load; a contact area detection sensor, provided to the fixed element, for detecting the contact area of the detected part D; and processing means for calculating the external load from an sensor output by using the correlation between the external load and the contact area.

A tapered roller bearing includes: an outer race including an outer raceway surface; an inner race including an inner raceway surface and a larger collar surface which is a concave curved surface; and tapered rollers provided between the outer and inner races, each of the tapered rollers including a tapered surface and a larger end surface which is a convex curved surface communicating with the tapered surface and corresponds to the larger collar surface.

A sealing device comprises a sealing member brought into contact with a contact surface so as to be slidable in a predetermined sliding direction. The sealing member comprises a sliding contact portion containing a high polymer material to be brought into sliding contact with the contact surface. A plurality of recessed or protruding streaks, which are independent of one another, are provided side by side so as to constitute a column on a surface of the sliding contact portion.
