In the third embodiment, partition members 21a, 121a are provided in the insertion holes 21, 121, whereas in the third embodiment, the insertion holes 221 are provided. Is a simple circular hole, and the boss 21 is inserted through the insertion hole 221.
A partition member 211a is formed in the hollow part of the first part. With such a configuration, the notch is eliminated from the boss 211, and the boss strength is increased. Particularly, as shown in the illustrated example, the partition member 211a is attached to the boss 21.
In the case where the partition member 211a is formed in the entire height direction, the boss strength is further increased because the partition member 211a has a function of a reinforcing material. Note that reference numeral 210 in the figure denotes a synthetic resin product, and 220 denotes an attached product.
