Abstract
An object of the invention is to provide a brake apparatus which can facilitate slope starting and slope climbing and which can be produced small in size and light in weight. In addition, another object of the invention is to provide a brake apparatus which can obtain a stable brake force under any conditions including running in the rain. The invention provides a brake apparatus in which a restriction is imposed on the rotation of a wheel () via a brake drum () provided on a rotational shaft of the wheel () so as to rotate together with the rotational shaft, the brake apparatus being characterized by comprising a brake shoe () for imposing a restriction on the rotation of the brake drum () in a forward or backward direction through wedge engagement with an inner circumferential surface of the brake drum () when the brake drum () rotates either in the forward direction or in the backward.
