The fitting step is a step of fitting the first leg portion 41 into the first groove 21 and fitting the second leg portion 44 into the second groove 25. The attachment method ends with the end of the fitting process.

  At the start of the fitting step, the operator aligns the first pressing portion 43 with the opening of the first groove 21 and aligns the second pressing portion 46 with the opening of the second groove 25 (see the upper part of FIG. 4). Thereafter, the operator presses the door stop 30 toward the first bottom surface 24 and the second bottom surface 28 (see the arrow described as “press” in the upper part of FIG. 4). With the start of the pressing, the door stop 30 moves to the bottom side in the depth direction. During the movement of the door stop 30, the first pressing portion 43 having the width W <b> 3 is compressed in the alignment direction between the first side surface 22 and the second side surface 23, and is deformed to the width W <b> 1 of the first groove 21. Similarly, the second pressing portion 46 having the width W3 is compressed in the alignment direction between the third side surface 26 and the fourth side surface 27, and is deformed to the width W1 of the second groove 25. The pressing is continued until the first base 35 and the second base 36 are in contact with the mounting surface S (groove edge regions R1, R2), and the door frame 20 and the door stop 30 are in the mounting state as shown in the lower part of FIG. The pressing ends at the timing. In connection with this, an insertion process is complete | finished.

  In the mounted state, the first base 35 and the second base 36 are in contact with the mounting surface S. The first pressing portions 43 are in close contact with the first side surface 22 and the second side surface 23 on both sides in the alignment direction. The second pressing portions 46 are in close contact with the third side surface 26 and the fourth side surface 27 on both sides in the alignment direction. A predetermined gap G is generated between the tip of the first leg portion 41 (first pressing portion 43) and the first bottom surface 24 of the first groove 21. The same predetermined gap G as that on the first leg portion 41 side is also generated between the tip end of the second leg portion 44 (second pressing portion 46) and the second bottom surface 28 of the second groove 25.
