Then, the foot length fixing screw 89 in the cylindrical body 78 is turned from the front surface 1b side of the door frame DF1, and the foot length fixing screw 89 is screwed into the door mounting wall W1 through the mounting hole 82 of the contact member 79.
Thereby, the contact member 76 is attached to the end surface 2a of the door mounting wall W1. In this case, in the actual construction work,
Preferably, when the foot length fixing screw 89 is screwed into the door mounting wall W1, it is not completely screwed to the end, and the screwing is stopped slightly before that. Then, after the clearance adjustment is completed, it is preferable that the foot length fixing screw 89 is completely screwed in. This is because the foot length fixing screw 89 is unlikely to come loose. However, even if the foot length fixing screw 89 is screwed from the beginning to the end, there is no particular defect.

In this embodiment, a foot length fixing screw 89 is used to fix the contact member 76. Instead of such a foot length fixing screw 89, a screw whose leg is not too long may be used. Further, in this embodiment, the cylindrical body 78 and the foot length fixing screw 89 constitute a fixing member. However, the fixing member may be replaced with the one composed of the cylindrical body 78 and the leg length fixing screw 89, and other fixing member as described in FIG. 4 may be used.

Next, the door D1 is attached to the door frame DF1, and then the door frame DF is adjusted to adjust the attachment position of the door D1.
1 and the gap between the door mounting wall W1 are adjusted. Gap adjustment,
This is performed by rotating the adjusting screw 77. When the adjusting screw 77 is rotated, the distance between the base member 75 and the contact member 76 changes as described above. The base member 75 is a door frame D
It is attached to the back surface 1c of F1 and the contact member 76 is attached to the end surface 2a of the door mounting wall W1. Therefore, if the distance between the base member 75 and the contact member 76 changes, the distance between the door frame DF1 and the door mounting wall W1 changes. In this embodiment, the distance between the door frame DF1 and the end surface 2a of the door mounting wall W1 is adjustable within the range of 8 to 40 mm (see FIGS. 12 and 13).

In this embodiment, the adjusting screw 77 and the cylindrical body 7
It is possible to make the interval with 8 relatively long. Therefore, the distance between the upper cylinder body 78 and the lower cylinder body 78 can be relatively widened, and as a result, the position distance at which the foot length fixing screw 89 of the contact member 76 stops can be separated. Thereby, the contact member 76 can be firmly attached to the end surface 2a of the door mounting wall W1.

Further, in the above embodiment, the base member 3 is attached to the front surface side of the door frame DF1.
It is necessary to make the width of the door so that it can be hidden by the door stop C2. On the other hand, the embodiment shown in FIG. 11 has no such limitation. Therefore, the width of the base member 75 can be widened, and the mounting intervals of the fixing screws 88 can be relatively separated, so that the base member 75 can be firmly mounted to the door frame DF1.

In each of the above-mentioned embodiments, the gap adjusting tool for the door which is rotated by the hinge has been described. However, the present invention can be mounted on the sliding door frame and used for opening / closing adjustment of the sliding door. Just in case.

According to the inventions of claims 1 and 2,
Only by operating the adjusting screw, the gap between the door frame and the door mounting body can be adjusted to adjust the door to a predetermined state.
As a result, there are excellent effects that the door frame can be attached and the opening and closing of the door can be adjusted easily and in a short time.

According to the third aspect of the present invention, the base member of the gap adjuster is attached to the back surface of the door frame facing the door mounting body. This back surface is usually covered with a decorative plate or the like and becomes an invisible part. Therefore, the base member can be formed large, and the base member can be firmly attached to the door frame. Also,
Since it is not necessary to form a large through hole for mounting in the door frame, there is no concern that the door frame will crack.

According to the invention described in claim 4, it is possible to perform an efficient door mounting and adjusting work using the gap adjusting tool according to any one of claims 1 to 3.
