Abstract: A manually operable hand braking device for such as but not necessarily confined to, a wheel (23) of a wheel chair. The device including a mounting member fixed adjacent the wheel periphery (23a), and a body part (5) mounted for partial rotation about an axis (7) of the mounting member (1) (2) extending transversely of the wheel (23); movement of the body part (5) being effected by a hand grip (26) and lever part (24), extending from the body part (5). The body part (5) being provided with two projecting spaced brake lock parts (21,22) disposed adjacent the wheel periphery (23a) or tire thereon, and arranged so that either of the brake lock parts (21 or 22) are engageable with the wheel periphery (23a) or tire on rotational movement of the body part (5), in one direction or the other, there being an intermediate position permitting freedom of rotation of the wheel (23).
