Claims

[Scope of utility model registration request]

A storage section attached to the body of the trailer, legs slidably inserted into the storage section up and down, an oil tank provided in the storage section, and a piston rod connected to the legs. A hydraulic cylinder fixed to the bottom wall of the oil tank with the hydraulic cylinder facing downward, a communication passage formed on the bottom wall of the oil tank connecting the hydraulic cylinder and the oil tank, and a communication passage formed in the bottom wall of the oil tank that connects the hydraulic cylinder and the oil tank, and A pair of check valves are installed separately and are connected to an air piston in an air cylinder, each of which allows fluid to flow freely from the oil tank to the hydraulic cylinder side and prevents fluid from flowing to the opposite side. an air pump having a plunger rod fixed to the ceiling wall of the oil tank by inserting the plunger rod into a suction hole opened in a communication path between the pair of check valves through the oil tank; and the air cylinder are connected via a valve to use air pressure in the oil tank to send the oil in the oil tank to the hydraulic cylinder, or to send air into the air cylinder to operate the air piston. An auxiliary leg device for a trailer or the like, comprising an air supply source that causes oil in an oil tank to be sucked into the suction hole by a plunger rod, and for pressurizes oil in the suction hole into a hydraulic cylinder by a plunger rod.
