<p>Disclosed is a structure for locking an electromagnetic clutch in a phase changing device of an engine, of which length in the axial direction of a camshaft is reduced compared with those of known structures. In a phase changing device (30) of an engine capable of changing a relative phase angle between a camshaft (45) and a crankshaft by braking a brake drum (34) using an electromagnetic clutch (35) locked on an electromagnetic clutch cover (70), the electromagnetic clutch cover (70) is provided with a holding portion (71) having a circumferential surface (71c) that is coaxial with the camshaft. The electromagnetic clutch (35) is held by the holding portion (71) via a substantially C-shaped plate spring (73) attached to the holding portion (71), and locked with respect to the holding portion (71) by first locking means (71e, 73a) formed between the electromagnetic clutch (35) and the holding portion (71) and second locking means (73b, 35d) formed between the plate spring (71) and the electromagnetic clutch (35).</p> |
