  • Patent number: 10126548
    Abstract: In a vehicle mirror, a heat generating body of a heater generates heat so as to heat a mirror body. A central side portion and an outer peripheral side portion of the heat generating body configure a thick portion and a thin portion, and the thin portion generates a smaller amount of heat than the thick portion, such that a heating density of the mirror body by the heat generating body is lower on an outer peripheral side portion of the mirror body than at a central side portion of the mirror body. Accordingly, the temperature of an outer peripheral portion of the mirror body can be suppressed from rising suddenly on progression from the outer peripheral side toward the central side of the mirror body, thereby enabling stress arising in the outer peripheral portion of the mirror body to be suppressed.
