PROBLEM TO BE SOLVED: To fit and connect an instrument movement to a circuit board, and a dial to the instrument movement in a single operation by fixing an analog instrument body only to the circuit board. SOLUTION: Locking pawl pieces 26 and locating pins 27 provided at each instrument movement 12 are engaged into locking holes 28 and positioning holes 29 provided in a circuit board 16. Locking between a movement case 25 and the circuit board 16, particularly the thickness direction of the circuit board 16, is maintained by locking action of the locking pawl pieces 26 and locking holes 28, and the dislocation of the movement case 25 in the plate face direction of the circuit board 16 is regulated by close fitting between the locating pins 27 and the positioning holes 29. Connection between the movement case 25 and the circuit board 16 can therefore be ensured in a single operation.
