Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing mechanism for a vehicle that is provided with an opening portion opened upward from a predetermined height at the rear of the vehicle body behind the driver's seat.

[Prior art]

Generally, in this type of vehicle, the open area at the rear of the vehicle body is covered with a hood or a plastic lid that is integrated with the roof and both side panels. In the case of a vehicle, in order to facilitate loading and unloading of cargo into the rear cargo compartment, the hood or lid can be removed to open the rear of the vehicle body.

[Problem that the invention attempts to solve]

By the way, in order to completely open the rear part of this type of vehicle, in addition to removing the hood, lid, etc., you must also remove the supporting members (portal pillars, frame members, etc.) that support them from the rear part of the vehicle body. Therefore, it is troublesome to remove and attach the support member, and it is also troublesome to store the support member in the vehicle after being removed.

[Means for solving problems]

In order to deal with these problems, the present invention provides a vehicle equipped with an open section at the rear of the vehicle body that is open from a predetermined height above the vehicle floor. A pair of front and rear gate-shaped pillars that straddle each other, and a closing member whose front and rear ends are fitted to guide rails provided in the vertical direction on both of these gate-shaped pillars so as to be movable in the vertical direction, thereby releasably closing the space between the pillars. a moving means for movably supporting the rear pillar in the longitudinal direction; a first driving means for driving the moving means to move the rear pillar in the longitudinal direction; The structure includes a second driving means that opens and closes the gap between the gate-shaped pillars and moves the rear pillar out of the moving path when the pillars are opened.

[Functions and effects of the idea]

As a result, in the present invention, if the second driving means moves the closing member downward to open the space between the gate-shaped pillars, then the first driving means drives the moving means for supporting the rear pillar. The rear pillar can be moved forward to be located behind the front pillar, and then the rear pillar can be moved rearward to return to the rear end of the rear portion of the vehicle body.

Therefore, the rear part of the vehicle body can be completely opened without removing the closing member and the rear pillar from the rear part of the vehicle body, and the troublesome work of removing, storing, and attaching supporting members such as the closing member and the pillar can be eliminated.
