Abstract
PURPOSE: To make waterproofing surely by providing a guide roller at the root thereof with projecting members for separating water and a space chamber having a drainage port and thus spattering invaded water into the space chamber with the centrifugal force of the projecting members.
CONSTITUTION: A cylindrical frame 2 is fixed to a shaft supporting metal 18 coaxially with a shaft 1 through a rubber packing 20. Inwardly projecting members 5, 6 are provided circumferencially along the inner peripheral surface 3 of the frame 2 while a drainage port 7 is provided at the lower portion of the frame 2. A cut-off portion 8 is formed in a part of the projecting member 6 and is communicated with the port 7. A guide roller 10 is provided coaxially with the shaft 1 through a bearing 9 and projecting members 13, 14 for rejecting water are provided on the outer peripheral surface 11 of the root portion of the rooler 10 so as to oppose to the projecting members 5, 6. Thus, a space chamber 17 is formed between the frame 2 and the roller 10 and is divided by the projecting members 13, 14 for rejecting water and the projecting members 5, 6. According to this constitution, invaded water is spattered into the chamber 17 by the centrifugal force of the projecting members 14 and is discharged through the port 7.
