Abstract
The boundary between the rolling surface 3a and the larger end surface 3b of a roller 3 and the boundary between the rolling surface 3a and the smaller end surface 3c are formed with rounded portions Rb and Rc, respectively. The rolling surface 3a and the rounded portion Rb associated with the larger end surface 3b are smoothly continuous with each other through a first arc R1, while the larger end surface 3b and the rounded portion Rb are smoothly continuous with each other through a second arc R2.
