Vehicle sunroof device

A vehicle sunroof device includes a movable panel, a guide rail, a sliding member, a check mechanism, and a lock-unlock switching mechanism. The check mechanism locks the forward and backward movement of the movable panel and brings the movable panel into a tilt-up state. The check mechanism includes a rotation check member having either an engagement groove or an engagement projection. When the movable panel moves to the tilt up state, the rotation check member is in a rotation position at which the rotation check member locks movement of the movable panel. In the tilt up state, when the sliding member moves further forward and then moves backward, the rotation check member pivots to move to a pivoting position at which the rotation check member unlocks movement of the movable panel.
