| 摘要 | A spiral unit includes a base tube extended along a longitudinal axis and made of a first thermoplastic resin, and a fin disposed on an outer peripheral surface of the base tube along a fin axis spirally extended around the longitudinal axis and made of a second thermoplastic resin. The fin includes a strip portion provided in a state of being bonded to the outer peripheral surface of the base tube and spirally extended along the fin axis. The second resin being mixed with a magnetic material in the strip portion. | ||

| 主权项 | 1. A spiral unit comprising: a base tube which is extended along a longitudinal axis, and which is made of a first thermoplastic resin; a fin which is disposed on an outer peripheral surface of the base tube along a fin axis spirally extended around the longitudinal axis, and which is made of a second thermoplastic resin, the fin including a hollow portion in which a cavity portion is formed along the fin axis; a strip portion which is provided in a state of being bonded to the outer peripheral surface of the base tube in the fin, and which is spirally extended along the fin axis on an inner peripheral direction side of the cavity portion; and a magnetic material which is mixed with the second resin in the strip portion, and which is configured to generate heat when vibrated to fuse the second resin. | ||
