  • Patent number: 11052736
    Abstract: A front link of a sunroof apparatus shifts, based on power transmitted from a first guide shaft of a front shoe, among a full-close corresponding position that allows a movable panel to be arranged in a full-close position, a front-up corresponding position that allows the movable panel to be arranged in a front-up position and a full-open corresponding position that allows the movable panel to be arranged in a full-open position. In a side view from a width direction of the front link, a first guide groove, through which the first guide shaft is inserted, extends so as to intersect with a line segment connecting a front connection shaft and a front support shaft.

  • Publication number: 20200276892
    Abstract: A front link shifts, based on power transmitted from a first guide shaft of a front shoe, among a full-close corresponding position that allows a movable panel to be arranged in a full-close position, a front-up corresponding position that allows the movable panel to be arranged in a front-up position, and a full-open corresponding position that allows the movable panel to be arranged in a full-open position. The front shoe check restricts power of the drive shoe from transmitting to the front shoe, when the drive shoe causes a rear link to shift between a collapsed position and a standing position.
