A sun roof device of a motor vehicle with a roof, comprising:

• means defining a sun roof opening in said roof;
• a lid member sized to cover said sun roof opening and having a weather strip disposed therearound, said lid member being capable of assuming a full close position relative to said sun roof opening wherein the weather strip on a front end of said lid member is pressed against a front edge of said sun roof opening;
• a guide rail extending along each side portion of the sun roof opening;
• a bracket secured to each side portion of said lid member;
• a front slide member slidably engaged with said guide rail;
• a pivot pin through which said front slide member and a front portion of said bracket are pivotally connected;
• a rear slide member slidably engaged with said guide rail, said rear slide member being formed with first and second cam grooves;
• a drive arm having an upper end pivotally connected to a rear portion of said bracket;
• lower and center cam followers connected to said drive arm, which are slidably engaged with said first and second cam grooves respectively, so that when said rear slide member is moved forward from a given position, said lid member is tilted up from said full close position lifting a rear end thereof from a rear edge of said sun roof opening and when said rear slide member is moved rearward from said given position, said lid member is tilted down from said full close position lowering the rear end thereof from the rear edge of said sun roof opening;
• and
• a cam groove member connected to said guide rail, said cam groove member having a cam groove with which said lower cam follower is slidably engaged for enforcedly separating the weather strip on the front end of said lid member from the front edge of said sun roof opening when said lid member is shifted from the full close position to the tilt-up position.
