Abstract: A three-wheel pedal-style wheelchair which includes a roller at a side, close to the ground, of the wheelchair, wherein the roller prevents the wheelchair from turning over, a steering wheel arranged at a side of the wheelchair, and two front wheels respectively arranged at two opposite sides of the wheelchair, wherein the two front wheels comprises a driving wheel led to rotate forward or backward by a user stepping and a loose wheel, wherein when the wheelchair turns to a direction in a small radius, the steering wheel is considerably rotated to a direction and the driving wheel is rotated forward, wherein when the wheelchair turns to another direction, the steering wheel is considerably rotated to a direction and the driving wheel is rotated backward. Accordingly, the wheelchair is easily controlled to have a small turn, like whirling in one spot, to move and to turn safely.

Abstract: An antislip material ejector comprises an antislip material container 12 which stores antislip material, an air inlet pipe 13 which is arranged in the antislip material container, a compressed air supply pipe 14 which supplies compressed air to the air inlet pipe, a nozzle portion 16 which is arranged in the air inlet pipe, a mixing pipe 17, which is connected with the air inlet pipe, in which the antislip materials are mixed with air and in which a suction hole 18 is formed through which the antislip material passes, a connecting pipe, one end of which communicates with the mixing pipe and the other end of which communicates with a cavity in the antislip material container, and an ejection pipe 20 which is connected with the mixing pipe and which ejects the antislip material together with the compressed air.
