Abstract

　少なくとも二枚のピエゾ素子が対向しているピエゾモーターに対して、ピエゾモーターの性能を低下させずに、ピエゾモーターに対する固定性を高めることができるピエゾモーター保持部材を提供することを目的とする。この目的を達成するため、第１ピエゾモーター保持部材２４は、第１ピエゾモーター２３の三枚のピエゾ素子２３３を囲むように構成されている。そして、第１ピエゾモーター保持部材２４の内壁面２４ａには、突起２４１、２４２が設けられている。これらの突起２４１、２４２は、第１ピエゾモーター保持部材２４の三枚のピエゾ素子２３３の節部２３３ａ、２３３ｂのみを保持するように構成されている。そして、第１ピエゾモーター２３は、これらの節部２３３ａ、２３３ｂのみで第１ピエゾモーター保持部材２４に固定された構造等を採用する。
