<p>PROBLEM TO BE SOLVED: To improve aritightness and to enforce strength between a connector and a water suction hose by attaching a cylindrical hoseband formed from a synthetic resin and the like to the joint part between a connector to a washing machine main body and a waterhose. SOLUTION: A connector 35 to the washing machine main body has a dent 35b to store adhesive or filler and a projection 35a to improve airtightness and to enforce strength between a water suction hose 27 and the connector 35. With or without applying pasting adhesive or filler to the connector 35, the waterhose 27 is connected. Then, to the outer surface of the connector-end of the waterhose, a hoseband 36 made of a synthetic resin is attached in a way as follows. Single or plural dents 35d at the hose-end 35c of the connector 35 and single or plural dents 36a of the hoseband 36 are mutually positioned. After such positioning, the hoseband 36 and the waterhose 27 are fused together by means of ultrasonic wave. Single or plural projections 36b at the inner side of the hoseband 36 are fused and fixed to the outer surface of the water suction hose 27.</p> |
