Abstract

PURPOSE: To prevent vibration at the time of high-speed rotation thru compact and simple constitution by a mechanism wherein a plurality of floating boards whose movement toward radial direction is regulated, are established slidably toward axial direction inside of an oil reservoir and providing movable boards interposed between the floating boards.
CONSTITUTION: Bearing seat 13 is fixed at the center of inner bottom surface of bearing-seat supporting body 12, which is housed in oil reservoir 11. And supporting body 12 has upper and lower projecting movable boards 17a and 17b on its outer edge and circular floating boards 18a and 18b are provided borizontally between these movable boards and above the upper board 17b. In this device, increase in vibration of bearing seat 13 produces oil pressure between movable board 17a and floating board 18a and also between 17b and 18b, which, surfacing 18b a little, forms oil layer 21, and thus an effect of restricting vibration is obtained.
