Abstract: A vehicle illumination device includes a light source and a long light guide body that extends linearly in a direction of entry of light from one end thereof disposed so as to be adjacent to the light source and radiates light from a linear light-emitting face, the light guide body having formed thereon projecting parts arranged in a longitudinal direction on a back face of the light-emitting face and extending in a direction orthogonal to the direction of entry of light. The widths of the projecting part vary in accordance with the distance from the light source. Provided is a vehicle illumination device that enables light emission with uniform luminance in the longitudinal direction to be realized while improving the productivity of a light guide body.

Abstract: There is provided a conveyance seat that suppresses the deterioration of the sensitivity of a load sensor to an input load even when a heater wire and the load sensor are disposed to overlap each other. A conveyance seat includes a seat cushion that supports buttocks of an occupant; a seat back connected to the seat cushion to serve as a backrest for the occupant; a load sensor provided at the seat cushion or at a portion of the seat back; a heater wire disposed on an occupant side with respect to the load sensor; and an intermediate member that positions the heater wire. The intermediate member is disposed between the load sensor and the heater wire.
