Abstract

A cage of a cage and rollers includes engaging projecting portions that are provided on outer circumferential surfaces of rim portions, the engaging projecting portions being configured to be elastically deformed when the cage is inserted into a support hole of a rocker arm to thereby allow the cage to be contracted in diameter and to be elastically restored to be brought into engagement with the rocker arm after the cage is inserted in the support hole, to thereby position the cage properly in relation to an axial direction relative to the rocker arm. The cage and rollers can be assembled to the rocker arm while being positioned properly in relation to the axial direction so that the cage and rollers and the rocker arm can be formed into a rocker arm unit, and the cage and rollers can easily be assembled to the rocker arm.
