Abstract

A heater apparatus includes a base member, a cover member supported by the base member, a cloth member provided between the base member and the cover member to hold a heater wire, and a heater temperature sensor brought into contact with the cloth member, covered on a base member side facing the base member and a cover member side facing the cover member with the cloth member, and configured to detect a temperature of the heater wire. The cover member has a cover recessed portion recessed towards the base member in an overlapping region where the cloth member on the base member side and the cloth member on the cover member side of the heater temperature sensor overlap.

Claims

1. A heater apparatus comprising:

a base member;

a cover member supported by the base member;

a cloth member provided between the base member and the cover member to hold a heater wire; and

a heater temperature sensor brought into contact with the cloth member, covered on a base member side facing the base member and a cover member side facing the cover member with the cloth member, and configured to detect a temperature of the heater wire, wherein

the cover member has a cover recessed portion recessed towards the base member in an overlapping region where the cloth member on the base member side and the cloth member on the cover member side of the heater temperature sensor overlap.

2. The heater apparatus according to claim 1, wherein the base member has a base recessed portion recessed toward the cover member in the overlapping region.

3. The heater apparatus according to claim 1, wherein the cover recessed portion is provided in a non-temperature-sensor-disposition region where the heater temperature sensor is not disposed in the overlapping region.

4. The heater apparatus according to claim 2, wherein the cover recessed portion is provided in a non-temperature-sensor-disposition region where the heater temperature sensor is not disposed in the overlapping region.

5. The heater apparatus according to claim 1, wherein the cover recessed portion is provided in a non-heater-wire-disposition region where the heater wire is not disposed in the overlapping region.

6. The heater apparatus according to claim 2, wherein the cover recessed portion is provided in a non-heater-wire-disposition region where the heater wire is not disposed in the overlapping region.

7. The heater apparatus according to claim 3, wherein the cover recessed portion is provided in a non-heater-wire-disposition region where the heater wire is not disposed in the overlapping region.

8. The heater apparatus according to claim 4, wherein the cover recessed portion is provided in a non-heater-wire-disposition region where the heater wire is not disposed in the overlapping region.
