Patent ID: 8857402

Claim:
An engine with a variable valve timing mechanism comprising: a cylinder block; a crankshaft rotatably supported by the cylinder block; a cylinder head mounted on an upper part of the cylinder block; a pair of intake and exhaust cam shafts rotatably supported by the cylinder head; a crank sprocket attached to the crankshaft; a pair of intake and exhaust cam sprockets attached to the intake and exhaust cam shafts; a timing chain wound onto the crank sprocket and the intake and exhaust cam sprockets; an actuator attached to at least one cam shaft of the intake and the exhaust cam shafts and configured to operate by an operating oil supplied from a hydraulic control valve to change a rotation phase of the cam shaft with respect to the crank shaft; and a chain case having both side portions in a width direction coupled to the cylinder block and the cylinder head and an upper end portion connected to a cylinder head cover, when the engine is seen in a crank axis line direction, and covering the timing chain, wherein the chain case is provided with an actuator cover part covering the actuator and bulging in the crank axis line direction along a mating surface with the cylinder head cover, a mount attachment part bulging in the crank axis line direction below the actuator cover part and connecting to an engine-side mount bracket, and a hydraulic control valve attachment part having the hydraulic control valve attached therein, wherein a fastener part fastening the chain case to the cylinder head is provided adjacent to the hydraulic control valve attachment part, wherein the mount attachment part is provided with a bracket attachment seat surface part to which the engine-side mount bracket is attached and is provided integrally with the hydraulic control valve attachment part below the bracket attachment seat surface part and in an inner side space part, and wherein the fastener part is disposed in the inner side space part of the mount attachment part and between the hydraulic control valve attachment part and the bracket attachment seat surface part.
