The upper frame support plate 1 is supported on the lower frame support plate 3 via a coil spring 13 with a gap 14 spaced therebetween in the diametrical direction of the coil spring.
A sealing material 15 made of oil-resistant rubber or the like is attached around the upper and lower frame support plates 1 and 3 to prevent dust and other foreign matter from entering the gap 14 between the upper and lower frame support plates 1 and 3, and both the upper and lower frame support plates 1 are attached. , 3 are tightened and connected by bolts 18.

のを確実に防止することができる。 The elastic support structure configured as described above has strong resistance to compressive forces that act in the vertical direction, and does not adversely affect the normal operation of machines such as presses, which occurs during machine operation. The vibration and/or impact energy generated by the machine is absorbed by the diametrical elastic deformation of each winding 12 of the coil spring 13 to sufficiently provide vibration isolation, buffering, and mitigation effects. transmission can be reliably prevented.
