Kind Code:
A1
Abstract:
In a valve gear (40), a gear part (41) that is rotated by drive torque transmitted from an actuator, a boss part (42) provided to the gear part (41) and having a cylindrical outer wall (425), and an extension part (45) extending from the gear part (41) in the axial direction on the radially outer side of the boss part (42), are formed in an integral manner. A coil-shaped spring (50) is fitted to the outer wall (425) of the boss part (42) of the valve gear (40). In the spring (50), a first hook (51) provided to an end portion on the gear part side and a second hook (52) provided to an end portion on the side opposite to the gear part are fastened to the sides opposite to each other in the circumferential direction of the extension part (45) . A valve gear subassembly (701) obtained by assembling the valve gear (40) and the spring (50) is stored in a valve gear storage chamber of a body (10), and the second hook (52) of the spring (50) is fastened to the body (10).
