Abstract:
1. A temperature detecting device comprising: a heat receiving plate that is exposed to an atmospheric gas so as to expand and shrink in accordance with a temperature of the atmospheric gas, and restrained at a rim portion thereof to generate a displacement of a central portion, which is surrounded by the rim portion, in a thickness direction thereof with respect to the rim portion in accordance with the temperature of the atmospheric gas; a displacement transmitting part that is displaced in accordance with the displacement of the central portion of the heat receiving plate; a deforming part that is deformed by a displacement of the displacement transmitting part; a deformation generating part that maintains a distance between the rim portion of the heat receiving plate and the deforming part; and a displacement detecting part that detects a deformation of the deforming part and outputs an electric signal indicating the deformation of the deforming part.
