Description

TECHNICAL FIELD The present disclosure relates to a sunroof apparatus. BACKGROUND ART Patent Literature 1 describes a sunroof apparatus including a movable panel that covers a roof opening of a vehicle, a drive shoe that moves in a front-rear direction, a rear link that supports the movable panel from below, and a first stationary block and a second stationary block that support the rear link. In the sunroof apparatus, the rear link has a first slide shaft and a second slide shaft extending in a width direction. The first stationary block has a first slide groove on which the first slide shaft of the rear link slides, and the second stationary block has a second slide groove on which the second slide shaft of the rear link slides. In the sunroof apparatus, when a force pushing the rear link rearward acts based on power transmitted from the drive shoe, the two slide shafts of the rear link slide on the two slide grooves. Then, the rear link rises, and a rear end portion of the movable panel is lifted up with respect to a front end portion of the movable panel. That is, the movable panel tilts up. CITATION LIST Patent Literature Patent Literature 1: U.S. Pat. No. 10,589,607 SUMMARY OF INVENTION Technical Problems In the sunroof apparatus as described above, it is necessary to provide at least one of the first slide groove or the second slide groove while tilting the slide groove with respect to a front-rear direction, in order to cause the rear link to rise when the rearward force acts. Therefore, at least one of the first stationary block or the second stationary block tends to be long in an up-down direction, and the thickness of the sunroof apparatus in the up-down direction tends to increase. Solution to Problems A sunroof apparatus according to one aspect of the present disclosure includes: a movable panel configured to be displaced between a fully-closing position at which the movable panel fully closes a roof opening of a vehicle and a tilt-up position at which a rear end portion of the movable panel is lifted higher than the fully-closing position; a guide rail extending in a front-rear direction of the vehicle; a rear support part disposed at a position closer to a rear end than a front end of the guide rail, the rear support part supporting the movable panel; and a power transmission member configured to move in the front-rear direction along the guide rail, in which the rear support part includes: a first rear link configured to rotate about an axis extending in a width direction of the vehicle; and a second rear link configured to rotate about an axis extending in the width direction in a state of supporting the movable panel, the first rear link is configured to rotate based on power transmitted from the power transmission member, and the second rear link is configured to displace the movable panel by rotating in accordance with rotation of the first rear link. Advantageous Effects of Invention In a sunroof apparatus, it is possible to reduce an increase in thickness thereof in an up-down direction.
