PURPOSE:To provide an inertia sensor for vehicle which is of high precision and with high sensitivity and which can be acieved at a low cost. CONSTITUTION:A signal outgoing terminal 3 is provided where a servo signal is led out from a signal terminal 2 for driving an optical pickup of an optical disc reproducing device which is mounted in a vehicle, wherein the outgoing terminal 3 is composed of an X-control signal terminal 5 to make X-direction control of the optical pickup in a plane and a Y-control signal terminal 6 to make Y-direction control of the optical pickup in the vertical direction. With these terminals 5, 6, respective signal component sensing parts 7, 8 are connected to sense the components having a shorter period than the servo period in association with the reproduction of optical disc, and only the components generated associated with behavior of the vehicle is emitted as the output. |
