Claims

[Scope of utility model registration request]

In a vehicle equipped with a pair of self-steering wheels rotatably supported by knuckles pivotally connected to both ends of an axle, a cylinder is fixed to the axle, and a piston is slidably inserted into the cylinder. a pair of air chambers consisting of;
a pair of bushing rods that are slidably supported by the boss portion of the cylinder and disposed within the cylinder so that one end can come into contact with the piston; and an arm that is integrally fixed to the other end of the bushing rod and the knuckle. and a pair of connecting members that connect and pivot the bushing rod, and when the air chamber is actuated, the bushing rod is slid by the piston to a position where the piston and the boss portion of the cylinder come into contact with each other, and the bushing rod is slid through the knuckle to A self-steering wheel fixing device, characterized in that it is configured to fix a steer wheel.
