Abstract

According to an aspect of the present invention, there is provided a temperature sensor mounting unit for mounting a temperature sensor to a mounting-target member at a mounting hole formed on a mounting wall thereof, the temperature sensor mounting unit including: a clip main body including: a base plate that is to be positioned on a front surface side of the mounting wall, the base plate having an installation hole formed therein, the installation hole allowing the temperature sensor to penetrate into a rear surface side of the mounting wall; and a plurality of elastic engagement pieces that extend from the base plate to be engaged with a circumferential edge of the mounting hole at the rear surface side of the mounting wall; and an elastic seal member configured to be disposed between the clip main body and the mounting wall.

Claims

1. A temperature sensor mounting unit for mounting a temperature sensor to a mounting-target member at a mounting hole formed on a mounting wall thereof, the temperature sensor mounting unit comprising:

a clip main body including;

a base plate that is to be positioned on a front surface side of the mounting wall, the base plate having an installation hole formed therein, the installation hole allowing the temperature sensor to penetrate into a rear surface side of the mounting wall; and

a plurality of elastic engagement pieces that extend from the base plate to be engaged with a circumferential edge of the mounting hole at the rear surface side of the mounting wall; and

an elastic seal member configured to be disposed between the clip main body and the mounting wall.

2. The temperature sensor mounting unit according to claim 1,

wherein the clip main body further includes:

a plurality of rib walls that are disposed between the plurality of elastic engagement pieces to be disposed along an inner circumference of the mounting hole,

wherein, in amounted state, the rib walls project a given length from the mounting wall at the rear surface side, and

wherein a cut-out portion is provided on a distal end of each rib wall.

3. The temperature sensor mounting unit according to claim 2,

wherein the elastic engagement pieces and the rib walls are formed to surround the installation hole so that, in the mouthed state, the temperature sensor is surrounded by the elastic engagement pieces and the rib walls.

4. The temperature sensor mounting unit according to claim 2,

wherein tongue pieces are provided on the inner circumference of the mounting hole,

wherein, in the mounted state, the tongue pieces are brought into abutment with the cut-out portions, and

wherein a bottom surface of the cut-out portion is positioned closer to the base plate than an engagement surface of the elastic engagement piece, the engagement surface being brought into engagement with the circumferential edge of the mounting hole.

5. The temperature sensor mounting unit according to claim 1,

wherein an accommodation portion is formed on the base plate to extend from the installation hole, and

wherein the accommodation portion has a bottomed cylindrical shape so as to accommodate the temperature sensor thereinside.

6. The temperature sensor mounting unit according to claim 4,

wherein, on each rib wall, a plurality of cut-out portions are formed as the cut-out portion, and

wherein, on each rib wall, depths of the cut-out portions from the distal end of the rib wall are different from one another.

7. The temperature sensor mounting unit according to claim 1,

wherein the elastic seal member is a washer made of an elastic material.

8. The temperature sensor mounting unit according to claim 1,

wherein the elastic seal member is an umbrella-shaped flange that expands obliquely outwards from a rear side of the base plate and that is formed integrally with the clip main body.
