<P>PROBLEM TO BE SOLVED: To enable to easily adapt an anisotropic material such as a quarts crystal to an angular velocity sensor lowered in the height in the rotational axis direction. <P>SOLUTION: The central part (boss part) 101 the three legs 121, 122, and 123 extending from the central part in directions different by 120 degrees of the same length, and rim part 103 connected with the outer side of each leg 121, 122 and 123. The legs 121, 122 and 123 are constituted with a piezoelectric material having at least three times symmetries while centering the prescribed axes in a plane having a normal line coincident with the axis. Each of legs 121, 122 and 123 is connected with the center part 101 and the other end of which is connected with the center part 101 and the other end is connected with the rim part 103. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
