This improves the slippage against the surface, further improving assembly workability. Additionally, due to the properties of the cured reactive hot melt agent, the mounting base can be securely attached to one member of the opening/closing mechanism, and the watertightness between the mounting base and one member is also increased. It becomes like this.
