To be able to uniformly pressurize a bearing at a desired amount of pressure and eliminate the need to carry out complicated works for controlling the amount of pressurization.
In a godet roller unit 1, a godet roller 2 and a motor 22 of a drive unit 4 are connected with each other via a shaft 5. Bearings 23, 24 rotatably supporting the shaft 5 are mounted to the right end and left end of the housing 21 of the drive unit 4, respectively. An air cylinder 25 comprising a piston 41 and a cylinder chamber 42 is disposed to the right of the bearing 23. The bearings 23, 24 are pressurized by the piston 41 pressing with a force according to the air pressure in the cylinder chamber 42. Also, the air pressure in the cylinder chamber 42 is controlled to be increased by the higher rotation speed of the godet roller 2 and by the higher tension of a yarn Y wound around the godet roller 2.
