PROBLEM TO BE SOLVED: To allow a track inspection device system to be mounted to a commercial operation vehicle without narrowing riding space of the commercial operation vehicle.SOLUTION: Both a detector unit 20 that detects a status of a track on which a commercial operation vehicle 1 travels, and a control unit 40 that detects, for inspection, a status of the track based on data detected by the detector unit 20 are mounted to the underfloor of the commercial operation vehicle 1 on vehicle bogies. Various components that constitute the detector unit 20 and control unit 40 that are mounted to the underfloor of the commercial operation vehicle 1 are mounted on an interior frame within a casing body of a rectangular parallelepiped shape. It is so constituted that, when an open/close door of this casing body is closed, water proofing and dust proofing packings provided on the casing body and the open/close door are brought to act cooperatively with each other to make a double packing structure, so that it has an extremely high degree of dew condensation prevention, water proofing and dust proofing properties. |
