Abstract

PROBLEM TO BE SOLVED: To reduce an influence on a temperature sensor due to penetration of the outside air by disposing the temperature sensor below an upper open/ closure member. SOLUTION: A sensor unit 4 for sensing the temperature in an on-vehicle insulating container is mounted in an article storage part 1a of the body 1 of the container. The container is mounted on a bed of a small truck to transport articles which are insulated in the body 1 to the destination. The front side of the container body 1 is brought close to the rear end of the truck and then an upper open/closure door 2 only is opened to take out the articles. At that moment, since the unit 4 is located below the door 2 in the body 1 and in the vicinity of the rear side of the body 1, even if the door 2 is opened, the air penetrating from the outside is prevented from easily reaching the unit 4. Thus, even if the door 2 is frequently opened and closed, an influence on the temperature sensor due to the penetration of the outside air can be reduced.
