2. Description of the Related Art For example, when two pipes made of plastic are connected to each other, or in a plastic water collecting basin such as a drainage basin or a rainwater basin, a plastic inflow pipe, an outflow pipe or a thrust stick is attached to a basin body Thermocompression bonding, an adhesive, or a caulking agent is known as a coupling means for coupling the adjusters made by the manufacturer. In the case of connection using thermocompression bonding, the two connection parts to be connected to each other are heated at the same time, melted and bonded. When connecting using an adhesive, an epoxy-based adhesive or the like is used, which is heat-cured or natural-cured for adhesion. When connecting using a caulking agent, butyl, acrylic, silicone resin, etc. are used.

[0003]

However, the above-mentioned conventional stoppers, joints, and water collecting basins have the following problems. (A) In the case of thermocompression bonding, the equipment is large and the work at the site is not easy. (B) When an adhesive is used, it takes a long time to apply and cure the adhesive, resulting in poor workability. In addition, thermal stress due to repeated thermal expansion and contraction due to temperature fluctuations and peeling due to external force I have something to do. In addition, the next work cannot be started until it is cured. (C) When a caulking agent is used, the caulking agent itself does not harden and therefore does not peel off, but the pull-out strength between the basin body and the adjuster is insufficient. (D) It is not easy to uniformly apply the adhesive or caulking agent, and the connection reliability is likely to be impaired.

Therefore, an object of the present invention is to provide a stopper, a pipe joint and a water collecting basin device which can shorten the installation work.
