PROBLEM TO BE SOLVED: To provide an apparatus for detecting a temperature of an underfloor device of a vehicle, capable of appropriately detecting the temperature of a heat generating part of the underfloor device from the ground side outside the vehicle by effectively reducing effects of disturbance by ambient environments of the vehicle traveling on a predetermined track, particularly snow, rain, or insolation. SOLUTION: A temperature detecting section 11 includes a case 111, a radiation thermometer 112 housed in the case 111, and a tube 21. The tube 21 comprises a double tube having an outer tube 211 and an inner tube 214, the outer tube 211 having a snow-shedding member 212 vertically arranged above a nose thereof. The front lower half of the outer tube 211 and the inner tube 214 is obliquely removed to form a notch 213. A plurality of small holes are bored through the bottom of the outer tube 211 and the inner tube 214 so as to allow the rain, and so on to fall down to the ground. The outer tube 211 and the inner tube 214 forming the double tube are mounted to the case 111 with a predetermined spacing. COPYRIGHT: (C)2010,JPO&INPIT |
