PROBLEM TO BE SOLVED: To provide a conveyor wheel easily, quickly and surely mountable without requiring frequent maintenance inspections and reduced in cost as compared with that of a conventional wheel. SOLUTION: This conveyor wheel 6 is provided with a boss part 8 and a wheel main body 9 fitted to a small diameter part 8a of the boss part 8. The boss part 8 is made of ultra-high polymer polyethylene resin , and the wheel main body 9 is made of polyether ether ketone resin. The boss part 8 is forcibly fitted into a horizontal shaft 1 via a hole part 7 provided in the boss part 8. The mounting of the conveyor wheel 6 on the horizontal shaft 1 is force fitted, and thereby the conveyor wheel 6 can be easily and quickly mounted. Since the ultra-high polymer polyethylene resin having a larger coefficient of linear expansion than that in polyether ether ketone resin is used for the boss part 8, fixing sureness is improved, and there is no possibility that the wheel main body 9 falls from the boss part 8.
