Present embodiment is that represent also can be to the example of the various researchs of nappe 3 except that the various embodiments described above.
Particularly, as shown in figure 29, also can on the nappe 3 with the relative portion 302 of carriage opposing backside surface side of vehicle component part on, with the portion of terminal of circuit element 21 and connector 22 from the formation position of the outstanding terminal leading section 211,221 that forms of dorsal surface 202 (with the face of element installed surface 201 opposition sides) of circuit substrate 2 accordingly, the cover part 305 of overshooting shape is set.
In this case, in the cold cycling of engine,, can prevent to chap at the periphery of terminal leading section 212 by being applied to the thermal stress of nappe 3.
And, as shown in figure 30, also can on the nappe 3 overleaf on the periphery of the relative portion of side 302 parts integrally formed collision prevent rib 34, this collision prevents that rib 34 is used to protect terminal leading section 211,221 not collided.In this case, prevent rib 34, can prevent the periphery of the collision terminal leading sections 211,221 such as equipment of outside by collision.
And, also can carry out following research, prevent from producing be full of cracks on the nappe 3, on the part that the root portion 223 (terminal part) that is installed in the connector 22 on the circuit substrate 2 is covered.
Particularly, as shown in figure 31, by being the obtuse angle with angle [alpha] between the relative portion 301 of face side that covers circuit substrate 2 in the part 306 of the root portion 223 that makes covering connector 22 on the nappe 3, thus the time to the dismounting of the wiring harness side-connector of connector 22, even when the periphery of the root portion 223 of connector 22 produces moment, also can relax in this part and produce the situation that stress is concentrated, and can prevent the generation of chapping.
In the present embodiment, be used for igniter 1 is installed to installation portion on the carriage 4, also can form by various structures in the same manner with the foregoing description 2.And in the present embodiment, other formation also can be identical with the foregoing description 1, and obtain the action effect identical with the foregoing description 1.
