Claims

[Scope of utility model registration request]

A ring-shaped valve body is formed on the end surface of the cylindrical body, and this ring-shaped valve body has a sealing surface on the axially outer side of the cylindrical body, and the sealing surface of the ring-shaped valve body abuts against the ring-shaped valve seat. In such a cylindrical valve, the ring-shaped valve body projects slightly outward in the axial direction from the cylindrical body portion, has a ring-shaped recess on the side opposite to the valve seat, and has a ring-shaped concave portion on the opposite side from the valve seat side. 1. A cylindrical valve comprising an elastic body such as rubber, the elastic body having an engaging portion that engages with an inner peripheral portion of an axially protruding portion of a ring-shaped valve body and a ring-shaped recess.
