A thermal insulation structure for a vehicle window device is provided with a heater is disposed on a vehicle interior side, a heat-receiving component that is provided between the window and the heater, and that, by receiving heat from the heater, imparts radiant heat to the window, and a thermal insulation layer that is provided at a surface of the heater on an opposite side from the heat-receiving component, wherein the thermal insulation layer is formed by mutually superimposing a plurality of thermal insulation materials, and of the plurality of thermal insulation materials, a thermal insulation material on a closest side to the heater has greater heat resistance than a thermal insulation material on a furthest side from the heater, and the thermal insulation material on the furthest side from the heater has a lower thermal conductivity than the thermal insulation material on the closest side to the heater.

Thermal insulation structure for vehicle window device

A photographing apparatus for vehicle includes a photographing apparatus receiving photographing light passing through a window, a heater that is a heating wire generating heat when receiving electricity, a heated portion to which the heater is fixed, and a pair of electrical supply lines that is connected to both end portions of the heater respectively and supply the electricity to the heater. The heated portion releases radiation heat to the window when receiving heat from the heater. An amount of heat generated by the both end portions per unit time is smaller than an amount of heat generated by the heater's portion other than the both end portions. The both end portions of the heater are positioned on outer peripheral side with respect to the heated portion when viewed in a thickness direction of the heated portion.

Photographing apparatus for vehicle and heating device

A photographing device for a vehicle includes: an imaging element configured to receive a photographing beam passing through a beam transmission section of a window section; a heater constituted by a heating wire; a section to be heated to which the heater is fixed, the section to be heated being opposite to an inner side surface of the beam transmission section; a switch element configured to switch electrical connection state to the heater; and a current limiting element disposed at the section to be heated and being configured such that current flowing through the heater becomes zero or is reduced when the electric circuit is short-circuited such that power is supplied to the heater while bypassing the switch element and a temperature of the current limiting element become equal to or higher than a predetermined value.

Photographing device for vehicle

The photographing apparatus for vehicle includes image pickup device which is disposed inside of a window part provided in a vehicle and receives photographing luminous flux passing through a light transmissive portion, a heater, composed of heated wire, generates heat when being supplied electrical power from electric power source, a heated portion, fixed to the heater, faces an inner surface of the light transmissive portion and gives radiant heat to the light transmissive portion when receiving heat from the heater. The heated portion is a plate having a polygonal shape. Both ends of the heater are positioned at two different corner portions of the heated portion.

Photographing apparatus for vehicle

An attachment structure for an in-vehicle camera includes a first bracket and a second bracket. The first bracket is fixed to an inner surface of a windshield. The second bracket holds an in-vehicle camera when the second bracket is attached to the first bracket at an attachment position. The first bracket includes a support portion and a first one-way engagement portion. The second bracket includes a pressing portion and a second one-way engagement portion. The pressing portion presses a pressed portion of the in-vehicle camera against the support portion and holds the pressed portion between the pressing portion and the support portion when the second bracket is at the attachment position. The second one-way engagement portion cooperates with the pressing portion to inhibit the second bracket from moving with respect to the first bracket when the second one-way engagement portion is engaged with the first one-way engagement portion.
