As described above, in a vehicle having a single door opening for two double doors, there is no pillar between the two doors, so that when a load is input to the roof side rail from above the vehicle. In addition, the roof side rail (roof rail) may be deformed downward, narrowing the living space of the occupants.

Therefore, the present invention has a door opening structure of a vehicle having a double door, which can suppress deformation of the roof rail when a load is applied to the roof rail from above and secure a living space for occupants. The purpose is to provide.

In order to solve the above problems, the first aspect of the present invention is a vehicle door opening structure in which one door opening provided on the vehicle body side is opened and closed by two double doors, which is a roof rail and a locking mechanism. And a striker and a tilt control member. The roof rail extends along the outer edge of the roof panel of the vehicle in the width direction of the door opening to partition the upper part of the door opening, and at least one of the two doors is closed. It has an intermediate region facing the upper end on the free end side from above . Locking mechanism is provided in the upper portion of the free end of one of the doors described above. The striker has a striker main body portion that is arranged below the lower end of the intermediate region of the roof rail and extends in the opening width direction, and is fixed to the roof rail so that a locking mechanism is activated when one of the doors is closed. It engages with the striker body from the outside of the passenger compartment and is locked to the lock mechanism. Tilt restriction member has a fixing portion that will be fixed to the intermediate area of the roof rail, the extension from the fixed part extending downward from the striker body portion, and a lower end from the lower end of the extension extending into the passenger compartment outwardly. The lower end of the tilt control member is inside the passenger compartment side of the upper end of the free end side of the one door below the engagement part between the lock mechanism and the striker main body with the one door closed. Close to the side.

In the above configuration, the lower end of the tilt control member is below the engagement portion between the lock mechanism and the striker main body in a state where one door (the door provided with the lock mechanism) is closed, and the one door is free. Since it is close to the inner side surface of the upper end of the end side on the passenger compartment side, a load is input to the roof rail from above (including the upper outside), and the roof rail is centered on the engagement part between the lock mechanism and the striker body. When deformed so as to tilt downward, the lower end portion of the tilt regulating member abuts on the inner surface of the upper end portion on the free end side of one of the doors. Therefore, in a vehicle having a double door, when a load is input to the roof rail from above, the tilt of the roof rail can be suppressed by the contact between the lower end portion of the tilt regulating member and one of the above doors, and the door can be suppressed. By efficiently transmitting the load to the side, it is possible to secure a living space for the occupants. For example, when the locking mechanism is fixed to the door reinforcement, the occupant's survival is achieved by efficiently transmitting the load to the door reinforcement when a load is input to the roof rail from above. Space can be secured.

The second aspect of the present invention is the door opening structure of the first aspect, which includes a protective member. The protective member is attached to the lower end of the tilt control member.

In the above configuration, since the protective member attached to the lower end of the tilt control member is provided, when the occupant gets on and off the vehicle through the door opening, the occupant's head collides with the lower end of the tilt control member extending below the striker. Even so, the protective member can protect the occupant's head.
