PURPOSE:To effectively prevent the vibration of an engine from being transmitted to a shouldering frame, by slidably supporting the end part of a resilient member, which holds the engine and made of metal or resin easily subjected to bending deformation, in the horizontal direction with respect to a slide surface provided in the shouldering frame. CONSTITUTION:An engine 3 is supported through a resilient member 10 formed in a particular shape. This resilient member 10, being made of metal or resin easily subjected to bending deformation, forms a plane shape like a starfish pattern, in which legs 10b, 10b... are extended in all directions from an engine mounting part 10a in the center, while the member 10 as a whole has a flat trapezoidal shape with an equal side as viewed from the front. While long holes are drilled in the radial direction from a vertical supporting shaft 11 serving as the center in the point end horizontal part of each leg 10b, 10b... of the resilient member 10, and its end part can be both freely moved a slight distance in the horizontal direction and resiliently deformed so that the engine mounting part 10a in the center may sink in the veritical direction. |
