Claims

[Scope of utility model registration request]

A main shaft, a wheel stay that can rotate in the axial direction of the main shaft with respect to the main shaft, a wheel supported by the wheel stay, and a wheel that has a larger diameter than the main shaft and can reciprocate in the axial direction of the main shaft. A brake lever drive device is provided on the shaft, and the brake lever drive device is pivotally supported on the wheel stay at approximately the center, and when the brake lever drive device moves in the direction of the wheel stay, one end comes into contact with the brake lever drive device, so that the other end is supported around the shaft by the wheel stay. The brake lever drive device moves in the direction of contact with the brake lever drive device, and the other end has both ends that weaken the contact with the brake lever drive device by moving the brake lever drive device in the direction opposite to the wheel stay, and the other end releases the contact with the wheel. A brake device comprising a brake lever.
