Abstract: At least a first movable coil part of a plurality of movable coil parts that is in the innermost place in the radial direction does not come into contact with both the fixed coil part, which is radially adjacent inwardly, and a second movable coil part, which is radially adjacent outwardly, at the same place in the circumferential direction while coming into contact with only one of the fixed coil part and the second movable coil part in a plurality of places that are circumferentially displaced, when the spiral spring is in an elasticity retaining state reached from a free length state by elastic deformation in the diameter-reducing direction.

Abstract: When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve is switched to a locking mode after the camshaft phase is controlled to a lock phase, and a lock pin is moved to a lock position. The camshaft phase is locked at the lock phase, and timing advance and timing retard chambers communicate with each other through a back space. In this state, a locking time filling control is executed. In the locking time filling control, the control mode of a hydraulic control valve is switched to a filling mode, the hydraulic oil is supplied to a timing advance chamber, both of the timing advance chamber and the timing retard chamber are filled with the hydraulic oil, the back space is filled with the hydraulic oil, and thereafter the control mode of the hydraulic control valve is returned to the locking mode.

Abstract: At least a first movable coil part of the plurality of movable coil parts that is in the innermost place in the radial direction does not come into contact with both the fixed coil part, which is radially adjacent on the inside, and a second movable coil part, which is radially adjacent on the outside, at the same place in the circumferential direction while coming into contact with only one of the fixed coil part and the second movable coil part in a plurality of places that are circumferentially displaced, when the spiral spring is in an elasticity retaining state reached from a free length state by elastic deformation in the diameter-reducing direction.
