Defrosting heater, and manufacturing method thereof |
摘要 |
A defrost heater, in which the strength of an insertion force needed for inserting a second glass tube in a plug is specified to be smaller than that needed for inserting a first glass tube in a plug. Thereby, dispersion in the insertion force needed for attaching the plug with a double glass tube can be reduced, and the assembling efficiency is improved.
