BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stop holding device for holding a door of a box type vehicle body at a predetermined opening.

[0002]

2. Description of the Related Art In a conventional door stop holding device disclosed in Japanese Utility Model Laid-Open No. 63-30564, a long groove and a locking hole located at one end of the long groove are formed in a regulating member fixed to the floor of a box-shaped vehicle body opening. And a bent portion at one end of the arm member is movably pivoted downward by a pivot support member on the inner surface of the door pivotally attached to the opening of the box-shaped vehicle body, and the bent portion at the other end of the arm member is provided with the long groove of the regulating member. And the bent portion at the other end is fitted into the locking hole when the door reaches a predetermined opening.

However, in this door stop holding device,
When the bent portion at the other end of the arm member is pulled out from the locking hole of the restricting member prior to the door closing rotation, the edges of the pivot member and the restricting member stick to the peripheral surface of each bent portion of the arm member. In order to prevent the movement from stopping, it is necessary to grasp the appropriate position of the arm member with one hand or both hands and lift it so as to move horizontally, which is not good in operability.

Further, since it is used outdoors, it is inevitable that the arm member, the control member and the pivot member are rusted, but the increase in the sliding resistance due to the rust further deteriorates the operability at the time of extraction. This increase in slip resistance prevents the arm member from moving downward by its own weight when the door is opened, preventing the bent portion from automatically fitting into the locking hole, and pushing the arm member down by hand to fit it into the locking hole. Since it is necessary to fit them together, the operability at the time of fitting is not good.

Furthermore, in the conventional device, the regulating member is fixed to the floor of the opening, and when the door is rotated to open the door over a certain angle, the arm member comes into contact with the side pillar of the opening. To fully open the door to 180 degrees or 279 degrees for convenient loading and unloading, it is necessary to grasp the arm member and pull it out from the long groove of the restriction member once, and when the door is closed and rotated, It is necessary to re-engage the bent end of the arm member with the long groove by hand during the process, and the operability at the time of full open use is not good.

[0006]
