PROBLEM TO BE SOLVED: To provide a motor drive unit capable of suppressing the movement of a machine due to vibrations, even if vibrations hard to be suppressed by a balancer and the like are generated and transmitted to a supporting leg portion.SOLUTION: A motor drive unit is equipped with a plurality of support leg portion 20 fixed on a bottom surface of a unit body 11 to be grounded. The support leg portion 20 is equipped with an elastic member 21 formed with an insertion hole 21d, a collar member 22 attached to the insertion hole 21d, and a shaft member 23 penetrating the collar member 22 and fixed to the unit body 11. At least one of the elastic members 21, is equipped with a deformation promoting portion 21e which is asymmetrically formed about the insertion hole 21d and enabling the shaft member 23 to easily incline in a predetermined direction.SELECTED DRAWING: Figure 3 |
