PURPOSE:To attain ease of the assembling work of a vibrator to a holder and to improve the assembly accuracy by connecting each piezoelectric vibrator with a connecting part prolonged in a direction at a right angle to the prolonged direction of a vibrator part. CONSTITUTION:The vibrator 1 is connected mutually to an adjacent vibrator with the connecting part 3 prolonged in a direction X at a right angle to the prolonged direction of the vibration part 1b at a base 1a, connected to a reinforcement frame 2 at both ends so that no connecting part 3 and reinforcement frame 2 exist among vibrators arranged in Y direction. Thus, vibrators connected in a line in the X direction are obtained by cutting off properly the reinforcement frame 2 at both ends in the X direction, fitted to a holder while keeping the block, and since no connecting part 3 exists at the bottom of the base 1a, no factor giving variation to the position accuracy exists in fitting. As a result, the assembling work of the vibrators to the holder is attained easily and the assembling accuracy is improved. |
