[0007] In some embodiments, a containing space is formed in the middle region of the wheel body, and the one-way bearing is fixed in the containing space.

[0008] In some embodiments, the inner side wall of the containing space is arranged in a gap with the outer ring of the one-way bearing.

[0009] In some embodiments, a fixing part is arranged in the containing space and fixedly matched with the one-way bearing.

[0010] In some embodiments, the fixing part is arranged between the outer ring of the one-way bearing and the inner side wall of the containing space.

[0011] In some embodiments, the fixing part is in abutment with the outer ring of the one-way bearing at one end and connected with the inner side wall of the accommodating space at the other end.

[0012] In some embodiments, the fixing part is a rod-shaped structure supporting the one-way bearing in the accommodating space.

[0013] In some embodiments, the fixing part is distributed equidistantly along the circumference of the one-way bearing.

[0014] In some embodiments, the wheel body is provided with a counterweight part coaxial with the wheel body and fixed on the wheel body on both sides.

[0015] In some embodiments, the pedal is rotatably arranged on the transmission rod.

[0016] According to the above, the beneficial effects of the technical scheme of the present application compared with the prior art are: the pedal and the wheel body are connected through the one-way bearing, when the pedal rotates forward, it drives the wheel body to rotate, and when the pedal is stationary, it does not have a transmission relationship with the wheel body, effectively avoiding the harm to the child's feet during the travel of the scooter.
