PROBLEM TO BE SOLVED: To provide a medical valve having novel structure that prevents a failure of an elastic valve body of falling-off to the housing inside.SOLUTION: A medical valve 10 is characterized as follows: a disc-shaped elastic valve body 16 is attached to an opening member 12 connected to a liquid flow path 102; a thin wall 70 formed in an outer peripheral portion of the elastic valve body 16 is sandwiched between claws 64 and 50 of the inside and outside of the opening member 12; also, an outer circumferential side of the thin wall 70 of the elastic valve body 16 is held by the opening member 12; and thereby, the outer peripheral portion of the elastic valve body 16 is supported by the opening member 12, and a male connector 100 can repeatedly be inserted to and removed from a slit 14 provided in a central portion 66 of the elastic valve body 16. A circumferential groove 90 extending in the circumferential direction on an inner circumferential side of the thin wall 70 in the inside surface of the elastic valve body 16 is formed of a depth larger than a bottom face 74 of the thin wall 70.SELECTED DRAWING: Figure 5 |
