PROBLEM TO BE SOLVED: To provide a medical valve having a novel structure which prevents the fallout of an elastic valve element at the time of inserting or ejecting a male connector.SOLUTION: While on both inner and outer surfaces of an outer peripheral part of an elastic valve element 38 are formed annular grooves 54 and 56 each of which extends in a circumferential direction, and a valve striker plate 68 is formed in an opening member, an annular ring 42 is assembled and fixed to the opening member from the opening side. On the valve striker plate 68 and the annular ring 42 are formed engagement protrusion sections 70 and 80 which can be engaged with the annular grooves 54 and 56 formed on both inner and outer surfaces of the elastic valve element 38. The engagement protrusion sections 70 and 80 are engaged with the annular grooves 54 and 56 formed on both inner and outer surfaces of the elastic valve element 38, and the engagement protrusion section 80 on the annular ring 42 has a plurality of protrusion shapes which are parted in a circumferential direction. |
