2. Description of the Related Art A movable assembly member comprising a first member and a second member movably mounted on the first member in a vertical or horizontal direction, for example,
For supporting various types of tables and tabletops so that the top plate can be adjusted in height and assembling columns, a pipe-like structure is used to position the moved second member with respect to the first member without shifting in the moving position. The second member in the first member
In addition to the configuration in which the member is housed, a screw is fixed to a screw hole provided in the first member so as to protrude the tip toward the second member, and the second member is appropriately moved with respect to the first member. After that, the screw is screwed forward, and the tip of the screw is pressed against the second member, so that the second member is positioned by the moving device. Further, the second member is housed in the first member having a pipe shape, and a concave portion or a hole is formed at an appropriate position of the second member, and a hole is formed through the first member. After moving the second member to a position where the hole and the concave portion provided in the second member coincide and face each other, a pin is inserted through the hole provided in the first member, and the tip of the pin is inserted into the second member. Means for positioning the second part agent at the moving position by being housed in the two member recesses is employed.

However, when the screw provided on the first member is pressed against the second member and positioned at the second member movement position, the tip of the screw is attached to the second member. If the second member can be moved to any suitable position with respect to the first member as long as the position can be pressed, the second member can be positioned at the movement position by the pressure contact, but the portion pressed against the second member Stays at the tip of the screw. For example, when the member supported by the first member or the second member is relatively heavy, the second member is pressed against the first member by the pressure contact. It was sometimes difficult to stably position the member. On the other hand, a hole is formed through the first member, and after the second member is moved to a position where the hole and the concave portion provided in the second member face and meet,
In the means for positioning the second component in the moving position by inserting a pin through a hole provided in the first member and storing the tip of the pin in the recess of the second member, the second member is moved in the moving position. On the other hand, if the second member is moved to a position other than the position where the hole provided in the first member and the concave portion provided in the second member communicate with each other, There was a disadvantage that the second member could not be positioned. The present invention has been proposed in order to improve such inconvenience. A first member and a second member provided to the first member so as to be movable in the vertical and horizontal directions are provided. It is an object of the present invention to provide a positioning structure in a movable assembling member that can fix and hold a second member at a desired position.
