Method of asembling rocker arms

摘要

Rocker arms are assembled by providing a plurality of holder members in series at a predetermined pitch and rotatably supporting the rocker arms by shafts which are supported by the plurality of holder members. First, rocker arm units are assembled by inserting into the rocker arms shafts which are longer than a distance between facing side surfaces of two pieces of the adjoining holder members. Then, the rocker arm units are set into spaces between respective holder members which are provisionally set at a distance which is larger than the predetermined pitch. This setting is made such that the axial line of the rocker arm shafts coincides with axes of bearing holes which are formed in the holder members. Then, the distance between the holder members is narrowed down to the predetermined pitch to thereby insert end portions of the rocker arm shafts into the bearing holes.
