Claims

[Scope of utility model registration request]

A rotating shaft is rotatably supported in the casing in a substantially horizontal manner through a tapered roller bearing, and the casing and the rotating shaft are connected to each other at the small-diameter open end of the inner hole in the outer race of the tapered roller bearing. Alternatively, the rotary shaft and the outer periphery of a second rotary shaft concentrically and rotatably fitted are liquid-tightly sealed via a seal member, and the space between the bearing and the seal member is filled with the A buttful plate in which the tapered roller bearing extends near the outer periphery of the rotary shaft or the second rotary shaft on the smaller diameter side of the inner hole in the outer race in the shaft support of the rotary shaft with which the lubricating oil supply path provided in the casing communicates. A structure of a shaft support of a rotating shaft, characterized by integrally comprising:
