Abstract: A vehicular door device causes a door to perform an opening-closing operation, based on an operation of a link mechanism formed of first and second link arms. Further, the first link arm is provided with a hand placement portion that rotates integrally with the first link arm. Then, the vehicular door device is configured in such a way that the first link arm supports a load applied to the hand placement portion.

Abstract: A vehicle slide door support device connects a slide door to a vehicle body. The slide door is configured to open and close a door opening formed in a side surface of the vehicle body. The device includes: a first guide rail arranged on a lower portion of the slide door and regulating a movement direction of the slide door; a first hinge unit arranged below the door opening and configured to move relative to the first guide rail in a longitudinal direction of the first guide rail; a second guide rail arranged above the first hinge unit on the vehicle body and regulating the movement direction of the slide door; and a second hinge unit arranged above the first guide rail on the slide door and configured to move relative to the second guide rail in a longitudinal direction of the second guide rail.

Abstract: A seat slide apparatus for a vehicle includes an upper rail, a lower rail, a lock mechanism including a lock lever that includes an engaging portion engageable and disengageable relative to an engaged portion formed at the lower rail, and an unlock operation inhibition apparatus including a mass member arranged at an inner void of the upper rail, a moving axis forming member forming a moving axis of the mass member, and a restriction portion inhibiting a movement of the mass member on the moving axis, the unlock operation inhibition apparatus restricting the engaging portion from moving to disengage from the engaged portion by the movement of the mass member on the moving axis to a position at which the mass member interferes with the lock lever in a case where a collision load greater than a retraining force specified for the restriction portion is input.
