To the insertion state. Thereafter, the top piece (111) is overlaid on the upper surface of the flange (21). Then, in this state, the through hole (113) of the top piece (111) is
The screw holes (21a) near the through holes (211b) are aligned with each other, and screws (13) and (13) are screwed into the corresponding portions to fix them. Thus, according to the above embodiment, the top surface piece (111) and the leg (112) are vertically connected via the second through hole (211b) formed in the flange (21). Therefore, when performing the work of attaching the positioning metal fitting (11) to the flange (21), the work can be performed while keeping the position of the eyes of the operator exclusively above the flange (21), and , Positioning bracket (11) and flange (21)
The work for fixing the work with the screws (13) (13) can be performed in a wide working space above the flange (21). Therefore, unlike the case where the positioning fitting (11) is mounted near the lower part of the flange (21), the flange (21) does not hinder the work, so that the mounting work of the positioning fitting (11) can be easily performed.

Next, as shown in FIG. 1, the positioning bracket (1
1) When the body case (2) with the (11) attached is dropped into the mounting opening (30A) of the countertop (TA), the legs of the positioning brackets (11) and (11) are in the initial stage of dropping.
(112) The inwardly inclined portion (112d) at the lower end comes into contact with the upper edge of the mounting opening (30A). Therefore, the leg (112) is gradually elastically deformed toward the body (23) of the main body case (2), whereby the main body case (2) is attached to the mounting opening by the guiding action of the inwardly inclined portion (112d). (30A) is dropped smoothly. When the main body case (2) is completely dropped into the mounting opening (30A), the tip of the retaining piece (114) formed on the pressing portion (112c) of the leg (112) is attached to the mounting opening (30A). (30A) is pressed into the inner peripheral surface of the

There is an effect that even if there is a manufacturing error in the opening size of 0A), the leg (112) is elastically deformed so as to absorb the manufacturing error, thereby enabling accurate positioning. The pressing portion (112c) (specifically, the retaining piece (1
14) does not come into contact with the inner peripheral surface of the mounting port (30A), and a slight gap is formed between them.
However, since no large displacement occurs in the mounting opening (30A), the main body case (2) is substantially positioned even in such a case.

Next, the fixing tool (4) is attached to the body part (23) so as to straddle the bottom plate (29) of the body part (23) and a pair of side plates (20) (20) standing from both ends in the left-right direction from below. (23), and in this state, the leading ends of the upright portions (42) and (42) of the fixture (4) are brought into contact with the lower surface of the countertop (T). Then, the through holes (44) (44) formed in the horizontal portion (43) of the fixing tool (4) are screwed into the screw holes (290) (290) formed in the bottom plate (29) of the main body case (2). ), And these two screws (6)
