強度が低いうえ、耐久性に劣る欠点がある。Problems that the invention aims to solve By the way, as shown in Fig. 7, the hollow top plate a with the shaft hole b has the disadvantage that the shaft support part has low strength and is inferior in durability. . Also, the 8th
In the case shown in the figure, since the shrinkage rate of the top plate a of the hollow body to be blow molded is higher than that of the bearing fitting e inserted during blow molding, the difference in shrinkage causes the plastic wall surrounding the bearing fitting to shrink. Cracks tend to occur around the shaft hole b of the part, and when drilling the shaft hole b with a drill during blow molding, cracks may occur due to heating due to friction with the drill bit and mechanical shock.
The plastic wall surrounding the bearing fitting e and the shaft hole b
Since cracks are more likely to form around the shaft, the strength of the shaft support is low and the durability is poor.
