Abstract
The durability and detection accuracy of a sensor unit may possibly decrease due to radiation heat generated from work pieces while they are welded together. A sensor deviceincludes a sensor unit, a housing case, and a shielding member. The sensor unitis a device for measuring the shapes of the work pieces W or the distance to the work pieces W. The housing casehouses the sensor unitand has formed therein a pass-through portionfor laser beam projection and a pass-through portionfor detection that pass a laser beam Lfrom a laser beam projection unitand a laser beam Ldirected to a detection unit, respectively. The shielding memberis attached to the housing case, and shields radiation heat directed toward the lower surface of the housing caseamong radiation heat generated while the work pieces W are welded together. The shielding memberis made of a material with lower thermal conductivity than that of the housing case
