PURPOSE:To simply attach and detach a busing by forming the thickness of the tapered part of a taper member to length capable of shifting a disk wheel and a transfer wheel from a hard connection to a soft connection. CONSTITUTION:A transfer wheel is constituted by fastening eccentrically a rotating wheel 15 having a belt groove part 15a to a supporter 13 keyed to a rotating shaft 11 by a bolt 16, fitting the taper member 14 of a bushing 1 into the conical opening 15f of a bushing receiving part 14c, simultaneously inserting the inserting port 14c to the rotating shaft 11 and fixing by an attaching and detaching screw means 17. The wedge part 14a of this taper member 14 has the taper face of thickness L1 formed, a plurality of vertically split slits and length enough to shift the rotating wheel 15 and the rotating shaft 11 from a hard connection to a soft connection. In such a way, the bushing can be simply attached and detached and the center of rotation of the transfer wheel and the center of the rotating shaft can be coaxially or eccentrically positioned. |
