Abstract:
PROBLEM TO BE SOLVED: To provide a brake member having sufficient friction resistance and capable of braking main wheels properly even in a wheelchair using solid non-puncture tires.SOLUTION: A brake member 100 comprises a disc part 101. One plate surface of the disc part 101 is a brake disc surface 101a pressed against a part of a side peripheral surface of a non-puncture tire 2. A circular recess 110, whose depth direction is a plate thickness direction of the disc part 101 and center is a center axis of the disc part 101, is formed on the brake disc surface 101a. When the brake disc surface 101a is pressed against the non-puncture tire 2, an inner peripheral surface of the circular recess 110 and a periphery of the circular recess 110 are pressed against an outer peripheral surface of the non-puncture tire 2, thereby braking the main wheel.SELECTED DRAWING: Figure 7
