PURPOSE: To attain ease of portability, by forming a reflector and a radiator so as to be folded.

CONSTITUTION: The reflector 2 and the radiator 1 are formed so as to be folded and extended/shrinked respectively. A supporting main rod base section 31 has the length so as to support the reflector 2 and the radiator 1 when they are shrinked. Supporting main rod extending/shrinking sections 32∼34 are provided to be folded to the base section 31. Supporting rods 5 extend the radiator 1 and support each part of the radiator to the base section 31 and the extending/ shrinking sections 32∼34. A connector 4 is provided to one end of the base section 31. Thus, a small space is attained for carrying, and ease of transportation is obtained.
