Claims

[Claims for Utility Model Registration] A cylindrical first joint member formed or fixed to a mating member to which the hose is connected is connected to a second joint member fixed to the end of the hose. The hose joint is connected to a mating member, and the second joint member includes an insertion tube portion that is inserted and fitted into the inner surface of the first joint member, and the insertion tube portion is locked in the insertion position by rotational operation. A locking mechanism is provided inside the second joint member, and a valve seat that protrudes radially inward from the inner circumferential surface of the second joint member, and a valve seat that is provided with a predetermined clearance on the inner circumferential surface of the center hole of the valve seat at the shaft-shaped portion. An on-off valve comprising a valve body that fits and is slidably guided by the inner peripheral surface of the second joint member at the large-diameter head and tail portions provided at both ends of the shaft-shaped portion. is assembled, and when the first joint member and the second joint member are separated, the head is forcibly seated on the valve seat by a spring means and is attached to the shaft-like part in proximity to the head. The O-ring comes into close contact with the inner circumferential surface of the center hole of the valve seat and blocks the passage in two stages, while when the first joint member and the second joint member are connected, the insertion tube end that abuts the tail part A one-touch joint for a hose with an on-off valve, characterized in that the valve body is pushed in the axial direction against the biasing force of a spring means to open the passage.
