PROBLEM TO BE SOLVED: To provide a vehicle refrigerant heating device including a seal structure that is preferable for securing a seal function.SOLUTION: An attachment member 35 of an insertion member (an electric heater 5d, a temperature sensor 23 for detecting a temperature of the electric heater 5d or a refrigerant, and bi-metal switches 22, 32) inserted into a tank body 6a is attached to an attachment hole 60, which penetrates through a lid body 6b formed as a container wall of a tank, so as to penetrate through the attachment hole 60. A vehicle refrigerant heating device includes: an O ring 38a which shields a gap space 40 between the attachment hole 60 and the attachment member 35 from the container inner side; and an O ring 38b which shields the gap space 40 from the container outer side. A communication hole 70 which allows the gap space 40 to communicate with a container exterior space is formed on the container wall.
【課題】シール機能を確保するに好適なシール構造を備える車両用冷媒加熱装置を提供する。【解決手段】タンク本体6a内に挿入される挿入部材(電気ヒータ5dや電気ヒータ5d若しくは冷媒の温度を検出する温度センサ23、バイメタルスイッチ22、32)の取付部材35をタンクの容器壁としての蓋体6bを貫通する取付穴60に貫通させて取付ける。そして、取付穴60と取付部材35との隙間空間40を、容器内側に対して遮断するOリング38aと、容器外側に対して遮断するOリング38bと、を備え、容器壁には、この隙間空間40を容器外側空間に連通させる連通孔70が形成されている。【選択図】図7
