ABSTRACT:
A lubricant sealed bearing, which is provided between a piston pin and a small end part of a connecting rod, comprises at least one rolling element and at least one grease standing ring. The grease standing ring is adjacent to an end portion in an axial direction of the small end part. A capacity of a grease pool defined by grease standing ring and an end side in the axial direction of the outer ring, is 40-60% of a theoretical amount of the grease extruded by the rolling element, the movement of the rolling element being caused by the movement of the piston from a top dead point to a bottom dead point and vice versa.
