Delivery ports 41a and 42a of the lubricating oil are arranged in a plurality of places in the carrying direction of this carrying passage 36. The installation number of delivery ports 41a and 42a is set in the same number as the group number when dividing the each optional number as one group among the whole cam lobes 13a and 14a equipped in camshafts 13 and 14. These respective delivery ports 41a and 42a supply the lubricating oil by straddling a plurality of cam lobes 13a and 14a included in the corresponding group. COPYRIGHT: (C)2008,JPO&INPIT
