A hot water tank cap for controlling a pressure for a hot water mat is provided to separate a pressure adjusting member from a coupling body so that the coupling body is easily cleaned. A hot water tank cap includes a cover(24), a coupling body(30), a pressure adjusting member(40), a pressure adjusting unit(50), and a pressing member(60). The cover is joined with an injection port of a hot water tank with its lower end opened and has a hole in its middle part . The coupling body has a fluid passage hole(33) so that steam is discharged to a central portion of a coupling member(31). The pressure adjusting member includes a shaft(42) extended from a middle part of an upper surface of a contact surface(41). The pressure adjusting unit has a lower part coupled to an inner circumference of the fluid passage hole. The pressing member presses the contact surface so that the contact surface is mounted on an inclination surface(34) of the fluid passage hole. |
