  • Patent number: 6412960
    Abstract: A mirror surface angle detector which can be used in common with a mirror surface angle adjusting device of a mirror. The mirror surface angle of the mirror is adjusted by oscillation of the mirror by the mirror surface angle adjusting device. The mirror surface angle detector for detecting the mirror surface angle of the mirror is provided separately from the mirror surface angle adjusting device, and is incorporated into the mirror surface angle adjusting device such that engagement claws provided at the mirror surface angle detector engage with engagement holes provided at the mirror surface angle adjusting device. When the mirror surface angle detector is removed from the mirror surface angle adjusting device, the mirror surface angle adjusting device can also be used in a type of vehicle which does not have a mirror surface angle detector in the mirror surface angle adjusting device. Therefore, vehicles of different types can make common use of the mirror surface angle adjusting device.

  • Patent number: 5044740
    Abstract: A mirror assembly including a mirror and a mirror holder for holding the mirror from behind. The mirror has chamfers formed in the fore and back peripheral corners of the mirror. The foreside chamfer is so dimensioned that a light ray incident upon the mirror and reflected by a reflective film at its outer periphery (the border between it and the inward edge of the backside chamfer) toward the outer periphery side of the mirror is incident upon the foreside chamfer for preventing glare. The backside chamfer is so dimensioned that a light ray incident upon the mirror and reflected by its outer peripheral side face toward the reflective film side is incident upon the backside chamfer for preventing glare of the light ray incident upon the mirror, the portion directed toward the mirror's outer periphery side is incident upon either chamfer. Since these chamfers, formed by grinding, are opaque and ground glass-like, respectively, the light ray reflected outward thereby is soft and free of glare.

  • Patent number: 4915485
    Abstract: A door mirror assembly having a sealing arrangement between opposed faces of mirror stay and mirror case to seal a clearance therebetween. The sealing arrangement includes annular outer and inner flexible lip members projecting, respectively, from a curved end face of case in parallel and neighboring with each other. The outer lip member is slightly higher than the inner lip member to contact the opposed end face in a normal condition, that is, when centers of the curved end faces are concentrically arranged. When the center of the curved end face is erroneously arranged to be eccentric to the center of the curved end face so as to be too close to the stay, the inner lip comes to be in contact with the end face of the stay.

  • Patent number: 4826305
    Abstract: An outer mirror for use in a motor vehicle is designed to prevent or attenuate chattering vibrations which a mirror holder holding a mirror produces against a mirror visor. This outer mirror assembly is provided with a first vibration-preventive member which is used in the mirror holder and with a second vibration-preventive member which is housed in a mirror visor and held in slidable contact with the first vibration-preventive member. The slidable surface of the first vibration-preventive member forms a curve which satisfies a condition that the inclination .alpha.' of the tangential line at each contact point of the two vibration-preventive members is always larger than the angle of friction .lambda. between the two vibration-preventive members. According to this structure, the first vibration-preventive member or the mirror holder is always given an outwardly acting force by the second vibration-preventive member which is provided with a spring.
