PURPOSE:To eliminate excessive parts such as a stopper, by making vertical elastic modulus of a resilient supporting tool at a corner section corresponding to the tension side of a belt entrained over an output shaft of an engine larger than those of other resilient supporting tools. CONSTITUTION:Resilient supporting tools 9b, 9c, 9d for an engine have the supporting directions directing toward the center of gravity of the engine 2, while a resilient supporting tool 9a for supporting a portion corresponding to the tension side of entraining belts 16, 17 has the supporting direction directing upward by an angle alpha with respect to the direction passing through the center of gravity G. Consequently. the resilient supporting tool 9a which is a same part as other resilient supporting tools 9b, 9c, 9d has a larger vertical elastic modulus than those of the resilient supporting tools 9b, 9c, 9d.
