Abstract

A sensor device includes a mounting board having a first rigid board on which an angular velocity sensor is mounted and a third rigid board on which an angular velocity sensor is mounted, and a pedestal for fixing the mounting board. Further, the pedestal includes a base section having a first fixation surface along an x axis and a y axis, and projecting sections disposed on the base section, and having a second fixation surface along the x axis and a z axis, and a third fixation surface along the y axis and the z axis, each of the rigid boards is supported by at least two of the first fixation surface, the second fixation surface, and the third fixation surface, and the angular velocity sensors have respective detection axes intersecting with each other.

Claims

1. A sensor device comprising:

a plurality of mounting boards on which a sensor component is mounted; and

a pedestal adapted to fix each of the mounting boards,

wherein when three axes perpendicular to each other are defined as a first axis, a second axis, and a third axis, respectively,

the pedestal includes

a base section having a first fixation surface along the first axis and the second axis, and

a projecting section disposed on the base section, and having a second fixation surface along the third axis and the first axis, and a third fixation surface along the second axis and the third axis,

each of the mounting boards is supported by at least two of the first fixation surface, the second fixation surface, and the third fixation surface, and

the sensor components have respective detection axes intersecting with each other.

2. The sensor device according to claim 1, wherein

at least one pair of the projecting sections are provided, and

at least one of the mounting boards is supported by the pair of the projecting sections so that the sensor component is located between the pair of the projecting sections.
