PURPOSE:To make vibration in a generating unit efficiently absorbable even in either of vertical and horizontal placements by installing two vibro-isolating members at both sides holding the center of gravity in between, on a straight line passing through the center of gravity of the generating unit, while installing another vibro-isolating member in direction of being crossed with these vibro-isolating members, in addition. CONSTITUTION:When a generating unit 7 is elastically supported in the inner part of an inner case 28 so as to be shown as being housed in an outer case 1 formed into a flat box form, a rubber vibro-isolating member 32 is interposed between a horizontal top face 31a of a receiving part 31 installed in this inner case 28 and the underside of a first stay 30. This vibro-isolating member 32 is positioned on a straight line X1-X1 passing through the center of gravity G of the generating unit 7 with a specified angle to an axis of a crankshaft 10, while it is set up at both sides holding the center of gravity G in between. Likewise another vibro-isolating member 37 is also interposed between a bottom surface 36a of another receiving part 36 and a second stay 35. This vibro-isolating member 37 is set up at both top and bottom sides holding the center of gravity G of the generating unit in between in a position of having the axis orthogonalized with the vibro-isolating member 32. |
