[Modification 4]
FIG. 7 is an exploded perspective view of Modification 4 in which the insertion / extraction screw is omitted and the connecting plate is divided into two parts.
The attachment structure of the lock box and the operation member according to the modification 4 is inserted into the pair of set pins 17a and 17a inserted into the fixing holes 13c and 13c of the cylinder lock 13 and the fixing holes 15c and 15c of the thumb turn 15. Each of the pair of set pins 17a, 17a is connected by two connecting plates 19A, 19A parallel to the front wall 25c.
Therefore, according to the mounting structure of the lock box and the operation member according to the fourth modification, the front wall 25c of the lock box 11 is penetrated from the end face of the door to the cylinder lock 13 inserted from the mounting hole 27 on the outdoor surface of the door. Thus, by inserting the pair of set pins 17a, 17a, the set pins 17a, 17a can be inserted into the fixing holes 13c, 13c of the cylinder lock 13 and the cylinder lock 13 can be fixed unremovably. Further, by inserting the pair of set pins 17a, 17a through the front wall 25c of the lock box 11 from the end face of the door to the thumb turn 15 inserted from the mounting hole 27 on the indoor surface of the door, the set pin 17a , 17a can be inserted into the fixing holes 15c, 15c of the thumb turn 15 to fix the thumb turn 15 so as not to be detached. Therefore, the fixing of the operation member, which has conventionally been performed by inserting four set pins one by one, can be completed by two pin insertion operations by simultaneously inserting a plurality of operation members at a time. As a result, the operation member can be attached in an easy operation and in a short time. Also, the set pins 17a and 17a for the cylinder lock 13 and the set pins 17a and 17a for the thumb turn 15 are provided independently on the two connecting plates 19A and 19A, respectively, so that other operation members can be fixed. Only one desired operation member can be attached and detached without loosening.
