  However, the mounting structure of the locking device disclosed in Patent Document 1 is provided with an opening in the frame side of the fence gate made of a metal pipe, and is stepped so that a part of the metal pipe is stepped. A process such as molding the frame side so as to obtain a shape or attaching a stepped metal member to the opening by welding or the like is required. For this reason, the mounting structure of the locking device disclosed in Patent Document 1 requires complicated processes such as mold forming and welding in its manufacture, making the manufacturing process more complicated, higher cost, and longer manufacturing period.

However, in this method of thinning the thin plate member as much as possible, a locking device that is intermittently loaded by the operation of the lever handle is attached to the thin plate member. Therefore, if the thin plate member is made too thin, the necessary rigidity is ensured. There is a problem that cannot be done.

  In addition, since the locking device mounting structure disclosed in Patent Document 2 is attached by a single thin plate member, the thin plate member depends on the vertical size of the locking frame surface opening to which the locking device is attached. It is necessary to change the size of. For this reason, the attachment structure of the locking device disclosed in Patent Document 2 cannot be manufactured by using a thin plate member in common, which increases the manufacturing cost of the thin plate member and makes it difficult to stabilize the quality. There is a problem of becoming.

  Therefore, the present invention has been devised in view of the above-mentioned problems, and the object of the present invention is that it can be easily manufactured and can be applied uniformly, and sufficient rigidity can be ensured.
