In a vehicle having an assisting mechanism, a back door stopper for restricting expansion and contraction of the rod can be attached to a rod of the back door assisting mechanism.

[0006] Thus, since the back door stopper is mounted on the back door assisting mechanism provided on the side of the back door, the back door opening can be used as it is, so that loading and unloading of the luggage becomes smooth. Further, since only the expansion and contraction of the rod is restricted, the rod can be shortened, and a long storage space is not required.

According to a second aspect of the present invention, the back door stopper is formed in a rod shape, and has, at both ends, mounting portions that can be mounted by sandwiching the rod.

Accordingly, since the rod is clamped and mounted, the work of attaching and detaching the back door stopper can be performed quickly, and the workability is improved.

According to a third aspect of the present invention, one of the mounting portions of the back door stopper is detachably engaged with the outlet end of the cylinder, and the other mounting portion is detachably engaged with the spherical bearing portion of the rod. I have.

[0010] Thus, the back door can be securely held in the fully opened state, and the attaching / detaching operation can be easily performed.

According to the fourth aspect of the present invention, the mounting direction of one of the mounting portions of the back door stopper differs from that of the other by 180 degrees.

[0012] Thus, first, one of the mounting portions is engaged and mounted from the rear to the front of the rod, and then the other mounting portion is clamped and mounted from the labor side of the rod to the rear. Since the mounting directions at this time are different by 180 degrees, a reliable mounting state can be obtained.
