PURPOSE:To provide a hot water valve seat with a degree of freedom, by making a hot water valve seat body swingable relative to a guide. CONSTITUTION:A force is applied to the hot water valve seat surface 8 of a hot water valve seat body 9. When the direction of the force is not parallel with the axis of the hot water valve seat body 9, it is swingable about a protrusion 33 in the direction of the force. Even if a control valve member 4 and a hot water valve seat 6 do not face each other completely in parallel, the hot water valve seat body 9 is swung in a guide 11 about the protrusion 33 so that the control valve member 4 is put in completely tight contact with the hot water valve seal 6 to shut off hot water. |
