Claim:
A sunroof device comprising: a roof panel which is provided to a fixed roof of a vehicle with the roof panel being openable/closable; a front slider and a rear slider which are connected to a front part of the roof panel and a rear part of the roof panel, respectively, through pin engaging units each of which is comprised of a lift guide groove and a lift guide pin which is slid along the lift guide groove, wherein the front slider and the rear slider are moved together to tilt up the roof panel by pressing action of the pin engaging units, and a driving motor which drives the front slider and the rear slider, wherein the lift guide groove of each pin engaging unit includes in a part thereof a horizontal groove for a tilt up completion position, and the lift guide pin of each point engaging unit is positioned in the horizontal groove when the roof panel is completely tilted up, wherein a horizontal stroke of the lift guide pin on a side of the front slider is set to be smaller than that of the lift guide pin on a side of the rear slider, the horizontal stroke of each lift guide pin being a stroke from a position when the roof panel is completely closed to a rear end of each of the horizontal groove, and the lift guide pin on the side of the front slider is positioned in the horizontal groove earlier than the lift guide pin on the side of the rear slider when the roof panel is being tilted up, and wherein the sunroof device further comprises: a rear guide rail which guides the rear slider; and a link arm of which one end is rotatably connected to the roof panel via a first connecting pin and of which the other end is rotatably connected to the rear guide rail via a second connecting pin, wherein a mid portion of the link arm is slidably engaged with the lift guide groove of the rear slider via a respective lift guide pin, wherein the lift guide groove of the rear slider presses the lift guide pin by the movement of the rear slider to raise or lay down the link arm, and wherein the rear guide rail includes an arch shape pin guide groove of which rotation center is approximately a position of the second connecting pin when the roof panel is completely closed, and the link arm is rotated to be raised or laid with its rotation center being the second connecting pin which is at a constant position, guided by the arch shape pin guide groove.
