Patent ID: 8562155

Claim:
An on-vehicle multidirectional visual-recognition device comprising: a first visual-recognition mechanism having a first attenuation factor, said first visual-recognition mechanism comprising: a door window for a front door of a vehicle; and a door mirror of a door mirror mechanism provided on a vehicle-body side portion, which includes the front door, in a vicinity of an outer side of the door window so as to show a rear side of the vehicle; and a second visual-recognition mechanism comprising: a first mirror provided in a door-mirror housing of the door mirror mechanism so as to show a range from a side of the vehicle including an area below the door mirror mechanism to a front side of the vehicle; a sub window to transmit light reflected by the first mirror and to extend continuously from the door window toward the front side of the vehicle via a frame; and a second mirror to reflect the light transmitted through the sub window toward a vehicle occupant, the second visual-recognition mechanism having a second attenuation factor substantially equal to the first attenuation factor of the first visual-recognition mechanism, wherein the first attenuation factor is a value obtained by adding a reduction rate based on a transmittance of the door window to a reduction rate based on a reflectance of the door mirror, wherein the second attenuation factor is a value obtained by adding a reduction rate based on a transmittance of the sub window and a reduction rate based on a reflectance of the second mirror to a reduction rate based on a reflectance of the first mirror, and wherein the transmittance of the sub window of the second visual-recognition mechanism is greater than the transmittance of the door window of the first visual-recognition mechanism.
