Abstract: A detector-attached vehicular lighting device includes a lighting unit and a detection unit. The lighting unit includes a light source and a lens. The lens is formed with a storage recess that is recessed in a counter-detection direction other than a detection direction. The detection unit includes a detector, a bracket, and a cover. At least a part of the detector is stored in the storage recess. The bracket supports the detector from a side in the counter-detection direction. The cover is provided with a flange that projects in the counter-detection direction. The cover is attached to the bracket by engagement of the bracket and the flange at a predetermined location of engagement. The detector has, at an end in the detection direction, a detection surface for detecting an object. The flange extends, above the detector, further toward the side in the counter-detection direction than the detection surface.

Abstract: Provided is a bracket attachment structure for detachably attaching a bracket to which a radar unit is attached to an outer lens. In the bracket attachment structure, the outer lens is attached to a lamp housing and constitutes a lamp chamber in which a lamp unit is disposed between the outer lens and the lamp housing, the outer lens includes a recessed part and an engaged part formed on an inner wall of the recessed part, and the bracket includes a bracket main body disposed in the recessed part, an engaging part provided on the bracket main body and inserted into the engaged part, an extension part extending to an outside of the recessed part and detachably fixed to an attachment partner, and at least one spring part disposed between the rear surface of the bracket main body and a bottom surface of the recessed part.

Abstract: A detector-attached vehicular lighting device includes a lighting unit and a detection unit. The detection unit includes a detector, a bracket, and a cover. At least a part of the detector is stored in a storage recess on a lens of the lighting unit. The bracket supports the detector from a side in a counter-detection direction. A flange of the cover is in engagement with the bracket. A gap is formed between an inner peripheral surface of the storage recess and the cover. A part of the inner peripheral surface of the storage recess, which is facing the gap, is provided with a lens side guide surface extending along an insertion virtual line heading from the gap toward a location of the engagement. A part of the cover, which is facing the gap, is provided with a cover side guide surface extending along the insertion virtual line.

Abstract: In order to enable the measurement of thermal property information about a subject, this thermal diffusion coefficient measuring device, which is used by contacting the surface of a living body, is provided with: a biological information sensor comprising a temperature sensor and a heat flux sensor; and a heating/cooling control means. The temperature sensor is provided at a position contacting the surface of the living body, and operates so as to detect skin temperature. The heat flux sensor is provided at a position contacting the surface of the living body, while being adjacent to the temperature sensor, and operates so as to detect heat flux on the surface of the living body. The heating/cooling control means enables the measurement of the temperature diffusion coefficient of a thermal resistance component that is present between the biological information sensor and a deep inner portion of the living body.
