<p>A camshaft phase variable device (100A) is provided to a camshaft (10) having a double structure, the camshaft (10) rotating according to an inputted drive force and comprising an inner shaft (11) and an outer shaft (12). The camshaft phase variable device (100A) is provided with a phase variable section (1A) having, within a single housing (2): an ignition advancing hydraulic chamber (R1) for totally advancing the phase of the camshaft (10) by hydraulic pressure; an ignition delaying hydraulic chamber (R2) for totally delaying the phase of the camshaft (10) by hydraulic pressure; and a phase difference hydraulic chamber (R3) for changing the phase difference between the inner shaft (11) and the outer shaft (12) by hydraulic pressure.</p> |
