Sensor Unit
First Claim
1. A sensor unit, comprising:
- a reference base;
a block that has a rectangular prism shape, that is positioned using at least a bottom face and one of side faces of the reference base as reference faces, and that is arranged on the reference base so as to be held upright relative to the reference base, wherein the block has a first face, which is parallel to the bottom face of the reference base, a second face, which has a certain positional relationship with one of sides of the reference base and which is orthogonal to the bottom face of the reference base, and a third face, which is orthogonal to each of the first face and the second face;
a first acceleration sensor that is fitted to the first face, and that detects an acceleration which acts in a direction in which a Z-axis extends;
a second acceleration sensor that is fitted to the second face, and that detects an acceleration which acts in a direction in which an X-axis extends; and
a third acceleration sensor that is fitted to the third face, and that detects an acceleration which acts in a direction in which a Y-axis extends, whereinthe X-axis, the Y-axis, and the Z-axis are orthogonal to each other.

Abstract
A sensor unit has a reference base. An acceleration sensor block and angular velocity sensor support rods are arranged on the reference base, using a bottom face and one side face of the reference base as reference faces. Three acceleration sensors, which detect accelerations that act in the directions in which an X-axis, a Y-axis, and a Z-axis extend, are fitted to three faces of the acceleration sensor block, respectively. Three angular velocity sensors, which detect angular velocities about the X-axis, the Y-axis, and the Z-axis, are fitted to boards that are fitted, via rubber bushings serving as vibration-proofing rubber members, to the angular velocity sensor support rods with screws, respectively.
