A control apparatus (30) controls supply of working fluid to advancing chambers (51-54) and retarding chambers (55-58). The control apparatus (30) alternately and repeatedly implements an advancing supply period, during which the working fluid is supplied to the advancing chambers (51-54), and a retarding supply period, during which the working fluid is supplied to the retarding chambers (55-58), at time of limiting a phase of a camshaft (2) relative to a crankshaft within a target phase range.
