Overheat protection device for movable body surface, overheat protection apparatus using the same and temperature control device

摘要

An overheat protection device for a movable body surface includes a thermal fuse having a fuse element which melts at a predetermined temperature, bridges electrodes in a pair and melts at a temperature equal to or higher than the predetermined temperature to break an electrical connection between the pair of electrodes, and a pair of long elastic bodies, to each of which one of the electrodes is electrically connected at an end or its periphery of the elastic body through a lead. At least one of pairs of upper surfaces and lower surfaces of the elastic bodies are spatially on a same plane.
