Claims

[Scope of Claim for Utility Model Registration] (1) A small-diameter flow path of a certain length with a valve seat at one end and a retaining wall at the other end is formed in the flow path, and the valve seat of this small-diameter flow path is A valve body that approaches and separates from the valve body is integrally provided with a retaining leg portion that passes through the small diameter flow path and is longer than the small diameter flow path, and the end portion of the retainer leg portion is connected to the retaining wall of the small diameter flow path. A check valve characterized by integrally forming an engageable locking part. (2) In paragraph 1 of the claims for utility model registration,
The retaining leg is an elastic retaining leg that has an outward expansion force, and the engagement force between the elastic retaining leg and the small diameter flow path causes the valve body to move in the direction of seating on the valve seat. A check valve that is powered. (3) In paragraph 1 of the claims for utility model registration,
A check valve in which a compression spring is inserted between the locking part of the retaining leg and the retaining wall of the small diameter flow path to bias the valve body in the direction of seating on the valve seat.
