PURPOSE:To reduce wear of a discharge pipe by sandwiching a slide plate between a leaf spring and the discharge pipe in a vibration restraining device. CONSTITUTION:Slide plates 21, 22 having hardness similar to that of a leaf spring 12 are sandwiched between the leaf spring 12 and discharge pipes 9, 10. Namely, the slide plate 21 is inserted between the upper surface of the trapezoidal leaf spring 12 and the discharge pipe 10. Also, the slide plate 22 is inserted between both opened ends 12c of the leaf spring 12 and the discharge pipe 9. As a result, the discharge pipes 9, 10 contact slide plates 21, 22 to increase substantially the contact area and reduce the contact surface pressure. Thus, since the discharge pipes 9, 10 slide the slide plates 21, 22 in operation of of the leaf spring 12, wear of the contact portions are substantially reduced. |
