The bolt 27 does not need to be a hexagon socket head cap screw, and may be a normal hexagon bolt or a set screw in which an operation recess is formed at the shaft end of the screw shaft.

  The latching groove 8 can be formed from the front end to the rear end of the lid receiving wall 6. If necessary, the latching recesses 8 can be formed with a group of recesses formed at regular intervals, and the latching position of the first fastening base 15 can be positioned while being changeable back and forth. For example, according to the front-rear position of the second fastening base 16, the first fastening base 15 is placed in the number of the locking recesses 8 counted from the front end or the rear end of the molding side groove 1, thereby The front-rear position can be properly positioned. The first fastening base 15 does not need to be formed in a strip shape, and can be formed in a rod shape, a tubular shape, or a pair of parallel rod-like bodies.

  By using the rotation preventing projections 22 and 23, the insertion limit when the engagement portion 24 is inserted and engaged with the engagement groove 8 can be defined. In that case, the locking protrusions 22 and 23 are brought into contact with the opposite end edges of the lid receiving wall 6 so that the insertion amount of the latching portion 24 is regulated to an appropriate amount, and the nut 21 is attached to both the receiving frames 4 and 4. It can be located in the center of the groove space between. Therefore, the screwing operation of the bolt 27 onto the nut 21 can be performed more easily. The receiving frame 4 can be formed in a L-shaped cross section with a vertical covering wall 5 and a horizontal lid receiving wall 6. The first fastening base 15 can be used in a state of being hooked on one of the left and right hooking grooves 8. In that case, the first fastening base 15 and the second fastening base 15 are fastened with the latching portion 24 at one end of the first fastening base 15 hooked to the latching groove 8 and the other end joined to the lower surface of the main bar 11. The base 16 may be fastened with a screw body 17. The fixing structure of the present invention can also be applied to a case where a grid-like slid lid is fastened and fixed to a catch frame of a water collecting basin.
