It is possible to secure a sliding point between the portion and the tip of the coil spring, and the structure can be simplified. Especially, when a plurality of coil springs are attached to the outer circumference of the pointer pipe, by using coil springs having different diameters, it is possible to secure the distance between them and avoid unnecessary contact between the coil springs.

果、導通不良を低減することができる。As described above, the guiding device of the present invention is
A coil spring made of a conductor is interposed between both conductive parts,
Since the end portion of the coil spring and one or both of the conductive portions are brought into sliding contact with each other, a gap is less likely to be formed at the sliding contact, and the stability and durability of conduction can be improved. That is, in the related art, since the spring piece formed by bending the lead frame made of a thin metal plate and the ring-shaped conductor are slidably contacted with each other, the elasticity of the spring piece is slow due to long-term use and wear due to the sliding contact. It was remarkable that the gap was formed between them, but in the present invention,
For such a spring piece, since a coil spring that is relatively excellent in elasticity is used, it is possible to efficiently suppress the formation of a gap at the sliding contact, and as a result, poor conduction. Can be reduced.

解消することができる。Further, if the end of the coil spring is in sliding contact with both conductive parts, the coil spring and the pointer and the like can be formed separately, and the handleability thereof can be improved. That is, in the prior art, since the spring piece and the pointer and the like are integrally formed, when the spring piece is deformed or worn, the spring piece and the pointer and the like had to be replaced together. However, since the coil spring is used, these components can be individualized and such inconvenience can be eliminated.

Since the coil spring is attached to the outer circumference of the pointer pipe that supports the pointer, the sliding point between the conductive portion and the tip of the coil spring is secured without providing an annular conductive portion like the conventional ring conductor. The configuration can be simplified. Especially, when a plurality of coil springs are attached to the outer circumference of the pointer pipe, by using coil springs having different diameters, it is possible to secure the distance between them and avoid unnecessary contact between the coil springs. As a result, it is possible to avoid a short circuit of a circuit configured using this.

Since the conductive part has a protrusion protruding toward the coil spring,
The area of the sliding contact can be limited to reduce the frictional resistance, and further, the durability against the abrasion of the conductive portion and the coil spring due to the sliding contact can be improved. Further, by providing such a protrusion, the coil spring is isolated from other conductive parts and is in a non-contact state, so that a short circuit of the circuit can be avoided.
