PURPOSE:To improve the transport efficiency by forming a low rigidity part by connecting the part between an elastic plate and a transport body by a connecting plate formed by laminating thin plates and reducing the load applied onto a vibrating body and increased the vibration amplitude of a vibrating body and a transport body. CONSTITUTION:A piezoelectric element 24 is driven by the ac voltage having the frequency equal to the characteristic frequency of the vibration system, and a carrier body 26 is vibrated in the slantly vertical direction by the vibration, and a transported article 27 is transported in the direction of arrow 33. Since an elastic plate 23 has a connecting plate 30 formed by laminating thin plates, the angle between a bimorph 22 and a trough 26 which varies with the vibration varies largely by the smooth and arcuate deformation of the connecting plate 30. Therefore, the degree of the application onto the piezoelectric element 24 of the load which is caused by said angular variation reduces markedly, and the amplitude of the piezoelectric element 24 is increased. Therefore, the transport speed and transport efficiency of the trough 26 can be improved.
