1. A sensor device for welding, comprising at least:
a sensor unit configured to measure states of work pieces to be welded together or a distance to the work pieces; and
a container including a housing case and a shielding member, the housing case being adapted to house the sensor unit, and the shielding member being adapted to shield radiation heat directed toward the housing case among radiation heat generated while the work pieces are welded together,
wherein the shielding member is made of a material with lower thermal conductivity than that of the housing case,
further wherein
the shielding member is attached to the housing case,
the shielding member has formed therein a planar portion and an attachment portion, the planar portion extending so as to shield the radiation heat, and the attachment portion being arranged on a rear face side of the planar portion that is opposite to a side where the work pieces are to be welded together and being adapted to attach the shielding member to the housing case, and
the shielding member is attached on the rear face side of the planar portion to the housing case via the attachment portion, and
further wherein
provided that the attachment portion of the shielding member is a first attachment portion, the housing case has a second attachment portion on the rear face side of the planar portion, the second attachment portion being adapted to attach the shielding member to the housing case,
each of the first attachment portion and the second attachment portion has a through-hole through which an attachment shaft is adapted to be inserted, and
the shielding member is attached to the housing case as the shaft is inserted through the through-hole of the attachment portions and through-hole of the housing case.
