One end of the mounting member 14 is in contact with the wheel 2 in a state of being coupled to the fixed portion 12 and a portion connecting one end of the mounting member 14 in contact with the wheel to the outer circumferential surface is formed in a curved shape have. The other end of the mounting member 14 is formed to be perpendicular to the outer circumferential surface, so that the adhesion of the disk 20 is improved and the contact area is formed to be wide.

A first engaging hole 141 and a second engaging hole 143 are formed in the mounting member 14. The fixing portion 12 is coupled to the first coupling hole 141 and the bolt 20a penetrating the disk 20 in contact with the mounting member 14 is coupled to the second coupling hole 143. [

The first engaging hole 141 and the second engaging hole 143 are connected to each other and the diameter of the first engaging hole 141 is larger than the diameter of the second engaging hole 143. An end 142 is formed in the mounting member 14 due to the difference in diameters of the first engaging hole 141 and the second engaging hole 143. [ However, the first coupling hole 141 and the second coupling hole 143 may not be connected.

The depth of the first coupling hole 141 is longer than the length of the fixing portion 12. However, the depth of the first coupling hole 141 may be equal to or shorter than the length of the fixing portion 12.

When the depth of the first engaging hole 141 is longer than the length of the fixing portion 12, when the mounting member 14 is engaged with the fixing portion 12, one end of the mounting member 14 abuts against the end 131 . When the one end of the mounting member 14 is in contact with the end 131, the mounting member 14 is no longer coupled to the fixing portion 12. A portion of the mounting member 14 where one end of the mounting member 14 and the first coupling hole 141 are connected to each other so that one end of the mounting member 14 is in contact with the end 131 when the end of the mounting member 14 contacts the end 131, As shown in FIG. However, one end of the mounting member 14 may be formed as an inclined surface instead of the curved surface.

The end of the fixing portion 12 can contact the end 142 when the mounting member 14 is engaged with the fixing portion 12 when the length of the fixing portion 12 is the same as the length of the first fitting hole 141 . When the end of the fixing portion 12 contacts the end 142, the mounting member 14 is no longer coupled to the fixing portion 12. [

On the other hand, when the disc 20 can not contact the mounting member 14 or the distance between the wheel 1 and the disc 20 needs to be adjusted in the structure of the wheel 1, A connecting member (not shown) may be coupled. The connecting member may be formed such that one side thereof is coupled to the second coupling hole 143 and the other side thereof is connected to the disc 20 and the bolt 20a passing through the disc 20 is coupled.
