Abstract

Provided is a vehicle door structure that enables manufacturing cost reduction and weight reduction. A vehicle door structure 1 includes a lock mechanism 40 . The lock mechanism 40 locks sliding of a slide door 6 in a fully closed position in which the slide door 6 closes a door opening portion 4 and in a fully open position in which the slide door 6 fully opens the door opening portion 4 . The lock mechanism 40 includes the portion to be locked 50 provided to the guided body 18 and the locking portions 60 and 70 provided to the slide rail 17 . The portion to be locked 50 protrudes toward the locking portions 60 and 70 and is locked by the locking portions 60 and 70 in the fully closed position or the fully open position.

First claim

What is claimed is:

1. A vehicle door structure comprising:
a slide door configured to open and close a door opening portion formed on a vehicle body;
a slide mechanism including a slide rail provided extending in an opening direction of the slide door and a guided body guided by the slide rail, the slide mechanism being configured to slide the slide door; and
a lock mechanism configured to lock sliding of the slide door in a fully closed position in which the slide door closes the door opening portion and in a fully open position in which the slide door fully opens the door opening portion, wherein
the lock mechanism comprises:
a portion to be locked provided to the guided body; and
two locking portions provided to the slide rail and each having a same configuration and arranged at a position that corresponds to the portion to be locked when the slide door is positioned in the fully closed position or the fully open position,

the portion to be locked protrudes toward one of the locking portions and the locking portions each have a configuration to accommodate the protrusion of the portion to be locked, thereby the portion to be locked is locked by the accommodation by the corresponding one of the locking portions in the fully closed position or the fully open position.

2. The vehicle door structure according to claim 1 , wherein the portion to be locked comprises:
a member to be locked having a rod shape and provided so as to be capable of protruding and retracting; and
a biasing member configured to bias the member to be locked toward the locking portions.

3. The vehicle door structure according to claim 2 , wherein the guided body comprises a roller rotatably supported by a support member that has a hollow and configured to move along the slide rail, and
the member to be locked is provided so that at least part of the member to be locked is positioned inside the support member and an extending direction of the member to be locked is aligned along a rotation axis of the roller, so as to be capable of protruding and retracting along the rotation axis.

4. The vehicle door structure according to claim 1 , wherein the portion to be locked retracts in accordance with operation of an operating portion configured to control opening and closing of the slide door and is released from a locked state with each of the locking portions.

5. The vehicle door structure according to claim 1 , wherein
the slide door opens and closes one partial area of the door opening portion,
the vehicle door structure further comprises a swing door configured to open and close a second partial area of the door opening portion together with the slide door that is in the fully open position, and
the slide rail is arranged on the swing door.
