Definitions

  • the first cylindrical portion 31Z provided above the spring portion 32Z piston-vibrates in the Z direction due to the bending vibration of the vibrating body 3Z. While the first cylindrical part 31Z itself is not deformed by the vibration and maintains its original shape, the end of the spring part 32Z is largely displaced. Stress will be concentrated at the connection portion S1 between the spring portion 31Z and the spring portion 32Z.
  • the magnitude of displacement is shown by the shade of hatching, and the darkly hatched part shows the part where the displacement is large, and the displacement is large in the part far from the node N.
  • the cross-sectional shape of the support portion 33 is S-shaped so as not to cause stress concentration on the vibrating body 3.
  • the cross-sectional shape of the support part 33 that connects the connecting part 31 and the vibrating part 32 is not limited to the S-shape, but if it is a curved shape, concentration of stress can be reduced. Therefore, it will be explained in detail whether the concentration of stress can be reduced to the extent of changing the radius of curvature of the vibrating body 3.
  • FIG. 6 is a schematic diagram for explaining the radius of curvature of the vibrating body according to the embodiment.
