Abstract:
1. An evaporated fuel treatment device for a vehicle comprising: a fuel tank for storing fuel; a fuel supply cap mounted on a fuel filling port of the fuel tank, the fuel supply cap being openable from and closeable to the fuel filling port by manipulation with a key inserted into a key cylinder; a key cover mounted on the fuel supply cap and covering a key hole of the key cylinder in an openable and closeable manner; an evaporated fuel storage unit storing evaporated fuel using an absorption agent; a charge passage allowing communication between the fuel tank and the evaporated fuel storage unit; a purge passage allowing communication between the evaporated fuel storage unit and an intake system of an internal combustion engine; a communication chamber formed in the fuel supply cap, the communication chamber allowing communication between the charge passage and an inside of the fuel tank; an open/close valve arranged in the communication chamber, the open/close valve being opened when an inner pressure in the fuel tank reaches a predetermined pressure such that the fuel tank and the evaporated fuel storage unit communicate with each other; and an interlocking member located between the key cover and the open/close valve, the interlocking member opening the open/close valve in an interlocking manner with an operation to open the key cover.
