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.

Claims

1. A mirror comprising:

a plate shaped mirror body; and

a heating section that is configured to heat a heated region in a plate face of the mirror body, wherein a heating density in the heated region of the mirror body is lower at an outer peripheral side of the mirror body than at a central side of the mirror body.

2. The mirror of claim 1, further comprising a heat generation body that is provided at the heating section, and that generates heat so as to enable heating of the heated region of the mirror body,

wherein, in the heated region of the mirror body, a cross-sectional area of the heat generation body is changed so as to change the heating density of the heating section.

3. The mirror of claim 1, further comprising:

a heat generation body that is provided at the heating section; and

a pair of electrodes that are provided at the heating section, and that supply current to the heat generation body such that the heat generation body generates heat and heats the heated region of the mirror body,

wherein the pair of electrodes have a space therebetween in the heated region of the mirror body, the space being changed so as to change an amount of heat generated by the heat generation body.

4. The mirror of claim 2, further comprising:

a pair of electrodes that are provided at the heating section, and that supply current to the heat generation body such that the heat generation body generates heat and heats the heated region of the mirror body,

wherein the pair of electrodes have a space therebetween in the heated region of the mirror body, the space being changed so as to change an amount of heat generated by the heat generation body.

5. The mirror of claim 1, wherein, in the heated region of the mirror body, the heating density of the heating section gradually decreases on progression from the central side of the mirror body toward the outer peripheral side of the mirror body.

6. The mirror of claim 2, wherein, in the heated region of the mirror body, the heating density of the heating section gradually decreases on progression from the central side of the mirror body toward the outer peripheral side of the mirror body.

7. The mirror of claim 3, wherein, in the heated region of the mirror body, the heating density of the heating section gradually decreases on progression from the central side of the mirror body toward the outer peripheral side of the mirror body.

8. The mirror of claim 4, wherein, in the heated region of the mirror body, the heating density of the heating section gradually decreases on progression from the central side of the mirror body toward the outer peripheral side of the mirror body.
