り目からふきこぼれの汁が浸入する別の問題が出る。The device for attaching a thermistor for a cooker is characterized in that a metal holder and a metal cap are provided with a detent. Some people mistakenly think that it is better to turn the metal cap body when it should not be turned, and some people turn it with oil and cut the lead wire of the thermistor. In the prior application, the metal holder and the metal cap body are provided with a detent to prevent this. However, in the prior application, there is a problem that the engagement is not sufficient because the projection b is not so resilient, and thus the product inspection is troublesome. Since the protrusions b are formed at the upper and lower intermediate positions on the peripheral surface of the metal cap body a, the elasticity is poor. When a cut is made in the protrusion b, elasticity is generated, but another problem arises in that the juice of the spilling-in penetrates from the cut.

がある。The thermistor mounting device for cookware of the prior application is:
Since the metal holder and the metal cap body are provided with a detent, the metal cap body does not rotate, thereby preventing the lead wire of the thermistor from being cut. However, in the prior application, since the protrusion b of the metal cap body is formed at an upper and lower middle position on the peripheral surface of the metal cap body a, the elasticity is poor, the engagement is insufficient, and the product inspection takes time. There is. However, in the present invention, the thermistor 12 is fixed to the lower surface side of the metal cap body 6, the metal cap body 6 is fitted to the upper end 2 of the cylindrical metal holder 1, and the bottom wall 5 of the metal holder 1 By providing a through hole 4 and inserting the upper end of the vertical fixed support cylinder 7,
At the upper end of the fixed support cylinder 7, a sliding plate 8 slidingly contacting the metal holder 1 is fixed, and a coil spring 10 is provided between the sliding plate 8 and the metal cap 6 to provide the metal holder 1. The outer surface formed by bulging the outer peripheral surface inwardly forms a concave vertical ridge 15, and the sliding plate 8 has a vertical concave ridge 16 that engages with the vertical ridge 15, The upper end of the ridge 15 does not reach the upper end 2 of the metal holder 1 to form a remaining portion 17 without a concave portion on the upper portion of the vertical ridge 15, and the lower edge 18 of the metal cap body 6 is bent inward to form the vertical ridge. Since the cap body attaching device of the thermistor for cookware in which the projection 19 which engages with the upper end of the ridge 15 is formed, not only the metal cap body 6 is prevented from rotating, but also
Since the vertical ridge 15 formed on the inner surface 9 of the metal holder 1 does not reach the upper end 2 of the metal holder 1 and forms a remaining portion 17 without a concave portion on the upper portion of the vertical ridge 15, the upper portion of the vertical ridge 15 is made of metal. An engagement projection 19 formed by bending the lower edge 18 inward is formed on a portion of the horizontal lower edge 18 of the metal cap body 6 facing the vertical ridge 15, which also serves as a concave portion for engaging the cap body 6. Therefore, there is an effect that an object which can be easily spread and easily engaged can be easily obtained.
