The present invention relates to a fuel tank-closable valve for a vehicle. The fuel tank-closable valve for a vehicle comprises: an upper case; a bobbin around which a coil is wound, and which is mounted inside the upper case; a core which has a plunger lifting passage with an open bottom, and is mounted inside the bobbin; a lower case which has a first passage communicating with a fuel tank, a second passage communicating with a canister, and an opening and closing passage between the first passage and the second passage, and assembled with the upper case; a plunger which is disposed in the plunger lifting passage, and rotates and lifts along a guide slot provided on the outer circumferential surface of the plunger lifting passage when a current is applied to the coil; a protruding unit which protrude from a lower portion of the plunger; a button unit which is disposed in a lower portion of the plunger lifting passage, and selectively opens the valve by transmitting a pressing force by the protruding unit when the plunger moves up and down; a first spring which is compressibly disposed between the plunger and a spring support plate; a valve driving plate which is mounted on a lower end of the core to be able to move up and down while keeping the plunger lifting passage airtight; and a valve body which has an orifice pipe for the first passage to communicate with the second passage, and is disposed in the opening and closing passage to be able to move up and down. Therefore, the fuel tank-closable valve for a vehicle can block a current from being continuously supplied, thereby preventing battery discharge.
