A pressure status display device displays whether positive pressure fluid or negative pressure fluid is being supplied in a fluid channel. A fluid guiding member (17) is constructed from a coupling body (11) where a fluid channel (12) is formed and from a partition member (16) provided outside the coupling body (11), and a receiving space (19) is formed by the partition member (16) and the coupling body (11). A pressure chamber (22a) communicating with the fluid channel (12) via a communication hole (23) is formed in the receiving space (19) by a sliding seal member (21) provided in the receiving space (19). When pressure is not being supplied to the fluid channel (12) by a spring member (25), a sliding sleeve (24) is positioned at a non-supply position, and when pressure is supplied, the sliding sleeve (24) moves to a supply position. The pressure status in the fluid channel (12) can be confirmed from the outside by observing the positions of the sliding seal member (21) and the sliding sleeve (24). |
