A plug includes: a fluid passage in a main body; a valve body biased to close an inlet of the fluid passage; a cover disposed on an upper end of the main body and closing an upper opening section thereof; and a control lever of the cover that can be pushed downward to open and close the valve body.
A plug includes: a fluid passage in a main body; a valve body biased to close an inlet of the fluid passage; a cover disposed on an upper end of the main body and closing an upper opening section thereof; and a control lever of the cover that can be pushed downward to open and close the valve body. An engagement claw section is formed on an elastic section of the main body. Provided on the cover is a transverse-plate upper surface for engaging the engagement claw section. A protrusion section of the control lever abuts against and shifts the elastic section in a disengagement direction when pushing the control lever downward. The protrusion section can thus disengage the engagement claw section from the transverse-plate upper surface. The control lever biased upward by the valve body allows the cover to be easily and lightly disassembled from the main body.
