Description of the Related Art Conventionally, as shown in FIG. 7, a door stop strut A is erected on one side of a passage portion R, and a door body B is made movable toward one side of the door stop strut A to make a door stop. A sliding door gate in which a door stop guide C having a U-shaped cross section is provided on one side of the pillar A, and a door stop end B1 of a door body is fitted into the door stop guide C to make a passage R closed is known. Has been. In such a sliding door gate provided with the door stop guide C, the door stop ends B1 of the door body B are joined to the door stop columns A along the guide walls C1 provided on both sides of the door stop guide C. The position of the door body B with respect to the pillar A can be kept constant, and the locking device D provided on the door strut A and the door body B can be reliably locked.

However, in the case of a gate in which the movement locus of the door contact end of the door body is regulated by a guide rail laid on the road surface, the door contact end of the door body can be accurately fitted into the door contact guide. In a so-called non-rail type gate having no guide rail laid on the road surface, it is necessary for an operator to fit the door main body into the door stop guide while correcting the positional deviation of the door stop end of the door main body. Normally, the door body is supported by a hanging post that stands upright against the door stop post across the passage, and the positional deviation of the door stop end of the door body occurs around the hanging post, and The edge is the part where the largest positional deviation is likely to occur, and the closing operation was extremely troublesome.

Further, since the guide wall of the door-contact guide has a plane shape along the moving direction of the door body, when the closing operation is performed in the state where the door body is displaced, the door-contact receiving portion is formed. The tip of the guide wall of and the door stop end of the door body collide,
The door stop guide or the lock device of the door body may be damaged. Therefore, an operator who closes the gate needs to join the door main body to the door-stop column while finely adjusting the position of the door main body so that the door-contact end of the door main body can be normally fitted into the door-stop guide.

Further, in a non-rail type electric gate apparatus which drives an electric motor to move the door body,
It is difficult to close the door body while finely adjusting the positional deviation at the door-stop end, and if the tip of the door-stop guide and the door-stop end of the door body come into contact with each other, there is a risk that even locking cannot be performed. Met.
