PURPOSE:To simplify structure and also to prevent film vibration of a front cover by tightening a central part of the front cover relating to an engine block, so that a mounting seat of a mount bracket can be integrally formed in the central part of the front cover. CONSTITUTION:A front cover 1 of an engine has a front wall part 11 and a peripheral wall part 12, and a power transmitting mechanism of containing a timing belt is covered with the front cover 1 between the front cover and an engine block, to fasten a mount bracket 2 to this cover 1. In this mount bracket 2, an engine block of insulator or the like is supported. Here, a boss part 14 is formed in the central part of a front wall part reverse surface 11b of the front cover 1. This boss part 14 is formed so as to protrude in a triangular shape from a front wall part 11 of the front cover 1, also to provide a junction surface 14a connected to the engine block 3, and a plurality of bolt holes 14b and further to provide a mounting seat 13 for bringing the mount bracket 2 into contact with a front surface of the boss part 14.
