To assure a holding state of a fitting member and to stably maintain the position and attitude of a sand collecting receiving frame for a long period of time by restricting the upward movement of the fitting member to make it less likely to come off the sand collecting receiving frame.
A fitting member 10 includes: an upper assembly member 2 and a lower assembly member 3; and a groove-shaped sand collecting receiving frame 4 provided in the lower assembly member 3 and having a bottom plate and lateral plates erected from both side ends thereof. The fitting member 10 has receiving frame holding plates 12 fitted to a peripheral wall rib 25 of the upper assembly member 2 and respectively engaged with upper end parts 4A of both lateral plates of the sand collecting receiving frame 4. Each of the receiving frame holding plates 12 includes: an upper engagement wall positioned above the upper end part 4A of the sand collecting receiving frame 4; and lateral part engagement walls positioned on both sides of the upper end part 4A. Thereby, the fitting member 10 holds the sand collecting receiving frame 4 relative to the lower assembly member 3.
