[0026]
As shown in FIG. 4, a template 7 is prepared in which a plurality of pairs of holes 71 are formed that match the round holes 322 of the plurality of pairs of screw cylinder mounting holes 32 in the rose plate 3. The pattern 7 is displayed near the center of each pair of holes 71 in the vicinity of each hole 71.
[0027]
Next, the attachment procedure of the door lock knobs 1 and 2 configured as described above will be described.
[0028]
A door lock 9 is fixed to the door 8. The door 8 is formed with a central hole 81 corresponding to the knob shaft insertion hole 31 of the rose plate 3 and a pair of guide holes 82 symmetrically with respect to the center of the central hole 81.
[0029]
The rose plate 3 is fixed integrally with the outdoor door lock knob 1 in advance in a state where the elongated hole 321 side formed on one surface side is disposed on the outer surface.
[0030]
First, since the distance between the pair of guide holes 82 of the door 8 differs depending on the door lock 9, the distance between the pair of guide holes 82 is grasped. That is, the pattern paper 7 is taken out, applied to the pair of guide holes 82 of the door 8, and a pair of holes 71 having a distance matching the distance between the pair of guide holes 82 of the door 8 from the plurality of pairs of holes 71 formed in the pattern paper 7. select.
