The oil storage chamber 35 is composed of a recessed part 36 provided in the protruding part 27 and a space surrounded by the chain tensioner closing the recessed part 36 while it is tightened in the protruding part 27. A branched passage 43 which is branched from the oil passage 34 to supply oil to a valve timing variable mechanism VVT which is oil supply destination different from the chain tensioner is provided.
