摘要： A probe case attached to a back plate includes a first elastic locking piece for coupling with the back plate and a second elastic locking piece for fixedly positioning a probe. When the first elastic locking piece is attached to the back plate in a state of not mounting the probe, the first elastic locking piece is brought into a tacked state of being coupled to the back plate attachably and detachably. Further, when the probe is mounted in the tacked state, elastic deformation of the first elastic locking piece is restricted by the probe to thereby bring about a locking state in which the probe case cannot be detached from the back plate. The second elastic locking piece includes a release operating portion for causing elastic deformation for disengaging engagement with the probe.
