Supporting structure for a vibrator

摘要

A vibrator 12 includes a regular triangular prism-shaped vibrating body 14. Center portions of two supporting members 18a and 18b are fixed to the vibrating body 14. One supporting member 18a includes a linear intermediate portion 20a extending in a widthwise direction (y-axis direction) of the vibrator 12, and two linear leg portions 22a and 22a bend downward from both ends of the intermediate portion 20a. In this case, a distance W' between tips of the two leg portions 22a and 22a is expanded wider than a length W of the intermediate portion 20a. Similarly, the other supporting member 18b also includes a linear intermediate portion 20b and two leg portions 22b and 22b, a distance between tips of which is expanded.
