Abstract
A metal-made coil spring is accommodated in a conduction hole of a spacer. A metal-made pin passes through a circuit support base, circuit board and spacer. A connection board is placed on a conduction hole of the spacer and fixed by a holding plate and a metal-made fixing screw. The coil spring has a height set greater than a thickness of the spacer. If the connection board is attached by the fixing screw, the coil spring is brought into a compressed state by the action of the holding plate and circuit board. Due to this, because the coil spring is strongly urged onto the circuit board and connection board, electric conduction is provided from the sensor unit to the circuit board.
