PROBLEM TO BE SOLVED: To allow a holding state of a mounting member to be ensured and a position or an attitude of a sand collecting receiving frame to be maintained for a long time by restricting the upward movement of the mounting member to make it less likely to come off the sand collecting receiving frame.SOLUTION: A mounting member 10 includes: an upper assembly member 2 and a lower assembly member 3; and a groove-shaped sand collecting receiving frame 4 mounted on a bottom plate body 30 of the lower assembly member 3 and having a base plate and lateral plates erected from both side ends of the base plate. The mounting member 10 has: engaging frame materials 11 mounted to a fitting part T between the upper assembly member 2 and the lower assembly member 3; and receiving frame holding parts 12 respectively engaging with upper end parts 4A of both lateral plates 42 of the sand collecting receiving frame 4. Each of the receiving frame holding parts 12 includes: an upper engagement wall 13 positioned above an upper end 4A of the sand collecting receiving frame 4; and side part engagement walls 14 positioned on both sides of the upper end 4A. Thereby, the mounting member 10 for holding the sand collecting receiving frame 4 to the lower assembly member 3 is provided. |
