An engine front structure, which is provided with a cover body (9a) of the timing cover (9) which covers the camshaft driving force transmission mechanism at a position opposed to a front surface of the cylinder head. An upper extension portion (9b) of the timing cover (9) extends upwardly from an upper portion of the cover body (9a) and has an inner surface formed with a depression (12, 13) receiving therein the variable camshaft timing mechanism (7, 8). A fastening seat (14) on the cover body (9a) with a relatively high stiffness is located beneath of the upper extension portion (9b) and centrally in a width direction of the engine and is fastened to the engine body. An engine-mounting-bracket receiving seat (16) is formed on a top surface of the upper extension portion (9b) to have a relatively high stiffness and attached to an engine mounting bracket. A connection portion (17) is provided on a central region of the inner surface of the upper extension portion (9b) in the width direction of the engine to extend along the depression (12, 13) and connect between the fastening seat (14) and the engine-mounting-bracket receiving seat (16) with a relatively high stiffness.
