PROBLEM TO BE SOLVED: To provide a caster of which main body and wheel can be easily replaced. SOLUTION: The main body 3 is constituted of the wheel supporter 31 supporting the wheel 4 and the fixing member 32. The fixing member 32 can not only be separated from the wheel supporter 31 both in the forward and backward direction, but also fixed to the front part of the same supporter 31 with the screw 51 in a way that it can be connected or disconnected. In the front part of the wheel supporter 31, the engagement slot 31a extending from the upper end to the lower end thereof is formed. On the upper plate 32a and the lower plate 32b of the fixing member 32, the engagement slot 32d and 32e are formed respectively. The engagement slots 31a, 32d and 32e constitute a fitting hole through which the engagement shaft of the support shaft 2 is inserted to fix the main body 3 to the support shaft 2.
