The force from a drive rod driven by an electric motor is transmitted via a link arm pivotally linked to the drive rod and a back door. When the back door is operated in an open direction, the link arm is supported by an open-side support slider and the acting direction of the force applied to the link arm by the drive rod is shifted to the opening direction of the back door. When the back door is operated in a closing direction, the link arm is supported by a closed-side support slider and a closed-side support roller and the acting direction of the force applied to the link arm by the drive rod is shifted to the closing-direction of the back door. The open-side and closed-side support sliders are pressed against the link arm by leaf spring members so that the link arm is prevented from oscillating between the sliders.

Automatic opening/closing apparatus for vehicle

The invention improves accuracy of engagement of a pinion and a rack with each other in an automatic opening/closing device for a vehicle. In the automatic opening/closing device for the vehicle and for automatically opening and closing an opening/closing member provided to a vehicle body, the device includes a motor for generating a driving force for driving a pinion for rotation, a sliding member having a rack engaged with the pinion, and a rail member for positioning the sliding member and for guiding the sliding member in a predetermined direction. The sliding member and the opening/closing member are connected through a connecting rod. A base member is integrally formed with a motor fixing portion and a rail fixing portion. The motor and the rail member are fixed to the base member. As a result, it is easy to improve accuracy of positioning of the pinion and the rack and to improve accuracy of engagement of the pinion and the rack with each other.

Automatic opening/closing device for vehicle

A powered tailgate system in which a direct driven rackis connected to one end of a rod, one end of a curved armis connected to the other end of the rod, the other end of the curved armis connected to a tailgate, an arm side slider portionwhich curves concentrically with the curved armis provided on the curved arm, and a plurality of load receiving portionstoadapted to be brought into sliding contact with the arm side slider portionso as to receive a load are disposed on a vehicle body side at intervals along a traveling direction of the curved arm

Powered tailgate system

An automatically opening/closing apparatus for vehicle of rack-and-pinion type is reduced in size and weight. The automatically opening/closing apparatus for vehicle is automatically opened/closed, by transmitting rotation of an electric motor to a back door through a drive power transmitting mechanism comprising a pinion and a rack. The rack is supported linearly reciprocably by a slide mechanism comprising a slide block and a guide rail. The slide block is formed to be sufficiently short to the entire length of the rack and the guide rail is accordingly formed to be short. Further, the rack is provided with a groove portion, and a holding member contacting with a holding face is disposed in the groove portion. Then, an interval between the rack and the opinion is maintained by the holding member, whereby engagement of the pinion therewith is ensured.

Automatically opening/closing apparatus for vehicle

An opening/closing apparatus including a trapping detection structure which reliably implements detection of trapping of foreign objects, even at a structure at which an outer peripheral edge of a moving body or an inner peripheral edge of an opening includes corner portions with small radii of curvature. A pressure sensor which detects external forces from directions intersecting a length direction thereof is provided at an outer periphery portion of a back door. However, at a corner portion, at a lower end portion of a door side portion or the like, the pressure sensor is provided with a large curvature such that the pressure sensor keeps distant from the corner portion. In place thereof, another pressure sensor, with a facing pair of electrode sheets, is provided along the corner portion. When one or more of these pressure sensors detects an external force, the back door is moved for opening.
