The vehicular storage device includes: a box-like storage member 4; a door 5 openably/closably turned relative to the storage member 4; and an open/close locking mechanism 6 capable of adopting the lock state for locking the door at a closure position relative to the storage member 4 and the release state for releasing the lock and allowing the turning of the door. The opening/closing lock mechanism 6 comprises a stopper member 1 disengageably engaged with the storage member 4 at an approximately central position of the door, and an operation member 3 arranged at a position near a driver's seat than the approximately central position of the door and operating the stopper member 1, and any of the stopper member 1 and the operation member 3 are mounted to the door 5. The stopper member 1 integrally has a lock part 11 engageable/disengageable with the storage member 4 at an approximately central position of the storage member 4; and a transmission part 12 for transmitting operation of the operation member 3 to the lock part 11.
