Angular velocity senor
First Claim
1. An angular velocity sensor for detecting an angular velocity of an object, the angular velocity sensor comprising:
- a tuning fork unit;
a base block provided with a terminal for outputting an output signal from the tuning fork unit to the exterior of the tuning fork unit;
a cover for housing the tuning fork unit in a space defined by the cover and the base block;
a circuit board for fixing the terminal on the base block, the circuit board being provided with a processing circuit for processing the output signal from the tuning fork unit; and
a casing for housing the base block, the cover, and the circuit board therein;
wherein the terminal on the base block is fixed to the circuit board, a clearance is defined between the base block and the circuit board, and the terminal on the base block is in the clearance and has a flexure portion;
wherein the flexure portion is made of a thin plate having a smaller thickness in a direction intersecting with a vibrating surface of the tuning fork unit than a thickness in a direction parallel to the vibrating surface; and
wherein the thin plate is produced by plastically deforming a cylindrical lead wire.

Abstract
An angular velocity sensor includes a tuning fork unit; a base block provided with a terminal for outputting an output signal from the tuning fork unit to the exterior; a cover for housing the tuning fork unit in a space defined by combination with the base block; a circuit board for fixing the terminal on the base block, the circuit board being provided with a processing circuit for processing the output signal from the tuning fork unit; and a casing for housing the base block, the cover, and the circuit board. The terminal on the base block is fixed to the circuit board, with a clearance being defined by the base block and the circuit board. The terminal on the base block in the clearance has a flexure portion, and the flexure portion absorbs a vibration of a high frequency applied from the exterior.
