A rear imaging device is provided. The rear imaging device is attached to a mobile object such as a vehicle, and is provided with an imaging device for imaging an area rearward of the mobile object, and a housing for housing the imaging device. At a rear end portion of the housing, drainer pieces are formed extending rearward. A plurality of the drainer pieces are formed in a circumferential direction of the housing. Tip end portions of the drainer pieces are formed narrower toward tip points thereof, with base portions of the adjacent drainer pieces being adjacent to each other.

This invention relates to a cold mirror for a head-up display apparatus and provides a cold mirror that enables suppression of a phenomenon of change in color tone of an image depending on a position from which the image is viewed. This invention also provides a head-up display apparatus including the cold mirror. In a head-up display apparatus, display light of an image displayed on a display is reflected by a cold mirror and a reflected image of the image is viewed by a viewer. A relationship between an incident wavelength and a reflection phase difference in the cold mirror is set so that the reflection phase difference falls within a range of 18060 degrees for an entire visible wavelength range of 420 to 680 nm.

This invention also provides a head-up display apparatus including the cold mirror. In a head-up display apparatus 10, display light 20 of an image displayed on a display 16 is reflected by a cold mirror 12 and a reflected image of the image is viewed by a viewer. A relationship between an incident wavelength and a reflection phase difference in the cold mirror 12 is set so that the reflection phase difference falls within a range of 18060 degrees for an entire visible wavelength range of 420 to 680 nm.


A hydrophilic member that enables provision of favorable photocatalytic performance while enhancing water repellent agent resistance and a method for manufacturing the same are provided. A maintenance method for removing a water repellent agent adhering to a surface of a hydrophilic layer of a hydrophilic member, the water repellent agent having a cation property, is provided. A photocatalytic layer is formed on a base material. An intermediate layer is formed on the photocatalytic layer. A hydrophilic layer having an isoelectric point exceeding 7 is formed on the intermediate layer. The intermediate layer is a layer that causes the hydrophilic layer to be formed so as to have a low density compared to a case where the hydrophilic layer is formed directly on the photocatalytic layer under the same film forming condition. A water repellent agent adhering to a surface of the hydrophilic layer can effectively be removed using sodium bicarbonate.

This invention enables obtainment of a reflectance variable element having a high cold tolerance. Two transparent substrates are disposed so as to face each other across a gap. On respective surfaces of the transparent substrates, the surfaces facing each other, respective transparent conductive films are formed. An electrolytic solution is charged in the gap. The electrolytic solution has a composition in which at least silver ions and copper ions, a content by weight of the copper ions being smaller than that of the silver ions, are contained in a non-aqueous solvent containing a non-aqueous solvent having a boiling point that is higher than that of methanol and methanol, a content by weight of the methanol being smaller than that of the non-aqueous solvent.


A casing of a turn signal lamp assembly includes a lamp housing and an outer lens, each of which includes a transparent member, being overlaid on each other and joined to each other at peripheral edges. The lamp housing includes a light entrance portion that receives incident light emitted from a light source, a light-guiding lens portion that guides the incident light, and a light exit portion that outputs the guided light.

The need for an O ring cover is eliminated when a gap between a shaft portion of a mover for mirror surface angle detection and a hole in a sensor case is sealed using an O ring. An O ring that allows a shaft portion of a slide block to be inserted therethrough is interposed between a sensor case and an actuator housing. The sensor case and the actuator housing are interconnected by means of screw-fastening via screws, and the O ring is brought into pressure contact with and held between the sensor case and the actuator housing by means of the screw fastening forces.

Moving a mover for mirror surface angle detection following a nut member along a male thread member in such a manner that the mover is rotatable relative to the nut member and is non-rotatable relative to the male thread member, without biasing the mover by means of a spring. A communication hole is provided in a male thread member along a shaft axis of the male thread member. A mover is inserted through the communication hole so as to be movable in an axial direction. A front end of the mover is connected to a position in a back of a front end of a nut member so as to be rotatable relative to the nut member around the axis of the nut member. A position detection device detects a position of the mover relative to a base member in a direction along the male thread member.
