That is, the width of the rectangular hole 43 is the same as the width of the irregularly shaped rectangular hole 37 formed in the base surface portion 35 of the seat plate member 31 (interval between the linear edges 37a and 37a). As described above, each flange portion 42 is provided with a long hole 40 into which the pin-like protrusion 38 of the seat plate member base surface portion 35 is inserted. When the leaf spring 32 is not deformed and maintains the normal state, the pin-like projections 38 are positioned closer to the outside of the long holes 40, 40 (FIG. 7), but when the leaf spring 32 is pressed and deformed, the pin-like projection 38 38 and 38 move toward the inside of the long holes 40 and 40.

  The adjustment screw 33 is inserted into the through-hole 18 of the vertical frame member 11 from the indoor side through the washer 44 brought into contact with the flat front end of the opposing protrusions 36 and 36 of the seat plate member 31 and screwed into the housing 16. It is. The diameter of the washer 44 is larger than the distance d between the pair of projecting portions 36 and 36 arranged to face each other, and smaller than the diameter D of the through hole 18 of the vertical frame member 11. In this way, the door frame adjustment tool 30 is fixed to the vertical frame member 11 by the screws 34, 34 and is fixed to the housing 16 by the adjustment screw 33, and between the vertical frame member 11 and the housing 16. The distance is adjustable through elastic deformation of the leaf spring 32.

  In order to attach the door frame 10 to the opening of the wall 23 using such a door frame adjusting tool 30, the width of the wall opening is about 10 mm and the height is about 5 mm with respect to the size of the door frame 10 in FIG. The door frame adjusters 30 and 30 are fixed with the screws 34 and 34 in the above-described manner at the approximate center positions in the height direction of the vertical frame members 11 and 12, respectively, and then the door frame 10 is opened to the wall. It arrange | positions on the floor base 25 of a part. Next, the adjusting screw 33 is screwed in the above-described manner, and the door frame 10 is temporarily fixed at an appropriate position of the wall opening while the vertical frame members 11 and 12 are vertically projected and the horizontal frame member 13 is leveled. At this time, it is preferable that a gap of about 5 mm is formed between the three-way frame members 11, 12, 13 of the door frame 10 and the housing 16. Next, arbitrary positions of the vertical frame members 11 and 12 (in the illustrated embodiment, three positions of an upper portion, a central portion, and a lower portion for each vertical frame member) and arbitrary positions of the horizontal frame member 13 (the left and right sides of the horizontal frame member 13 in the illustrated embodiment) At two locations near both ends, the timbers 21, 21... Have a thickness corresponding to the gap (e = about 5 mm) between the frame 16 (column or horizontal member) and each door frame member. . . And fixed by the fixing screw 20 (FIG. 5). Further, a floor plate 26 is laid on the floor base 25.

That is, the door frame adjustment tool 30 is fixed to the vertical frame member 11 with the screws 34 and 34 and fixed to the housing 16 such as a column with the adjustment screws 33 in the manner described above. Since the distance between the vertical frame member 11 and the housing 16 can be adjusted through elastic deformation, the position in the left-right direction in FIG. 1 can be adjusted. The leaf spring 32 is in a state (FIG. 7) in which the pin-like projections 38, 38 of the seat plate member 31 are accommodated near the outer side of the long holes 40, 40 when not being in pressure contact (FIG. 7). The positions of the pin-shaped projections 38, 38 in the long holes 40, 40 move inward. Accordingly, the adjustment allowance in the left-right direction is the movable distance of the pin-like protrusions 38, 38 given by the dimensional difference between the length of the long holes 40, 40 and the diameter of the pin-like protrusions 38, 38.

  Further, the adjustment screw 33 for fixing the door frame adjustment tool 30 to the housing 16 is a washer that is inserted through the hole 37 and the hole 43 having a size larger than the body diameter and is in contact with the flat end surface of the protrusions 36 and 36. Since 44 has a smaller diameter than the through hole 18 of the vertical frame member 11, the vertical frame member 11 can be finely adjusted in the longitudinal and vertical directions with respect to the housing 16 within a range allowed by these dimensional differences. . That is, in FIG. 2, the washer 44 has a diameter sufficiently smaller than the diameter D of the through hole 18 of the vertical frame member 11, so that the inside of the through hole 18 extends in the front-rear direction (vertical direction in FIGS. 2 and 3). Since the adjustment screw 33 passes through the screw insertion holes 37 and 43 having a size larger than the diameter of the body, the adjustment screw 33 can move in the front-rear direction within the range of the holes 37 and 43. Therefore, even if the adjustment screw 33 is screwed into the housing 16, the vertical frame member 11 is moved in the front-rear direction with respect to the housing 16 within the range allowed by the dimensional difference between the members. The position can be finely adjusted. Further, since the washer 44 is movable in the through hole 18 between a pair of opposed arcuate edges 37b, 37b of the odd-shaped rectangular hole 37 of the seat plate base surface portion 35, the adjustment screw 33 is attached to the housing 16. Even in the screwed state, within this range, the vertical frame member 11 is moved in the vertical direction with respect to the housing 16 (vertical direction in FIG. 2 and left and right in FIG. 3) to finely adjust its position. be able to.
