装箱11を貫通させて外部に突出させる。 The temperature-sensitive cylinder 6 consists of a first cylinder 6 1 made of a metal material with high thermal conductivity, and a cylinder 6 2 made of a synthetic resin with low thermal conductivity connected in the axial direction of the first cylinder 6 1 . 1 and 6 2 are located within the heat insulating material U 1 ,
The first cylindrical body 6 1 is attached tightly to the outer surface of the inner box 1 2 by welding or aluminum foil tape, etc. to ensure good heat conduction, and the second cylindrical body 6 2 is attached to the outer surface of the outer box 1 1 . Penetrate and protrude to the outside.
