摘要： A circuit board assembly and a method of manufacturing the same is provided, by which, when external pressure is applied to a cover, deformation of the cover caused by the external pressure is suppressed and no adverse effect is produced to electronic components on a circuit board. A cover of a circuit board assembly includes a first cover to cover a first surface of a circuit board and a second cover to cover a second surface of the circuit board. A projection portion projects from an inner surface of the first cover. When a complete circuit board assembly is formed by insert-molding using the circuit board assembly as an insert part, the projection portion suppresses deformation of the first cover and the second cover.

摘要： Provided are a circuit board assembly that can prevent contact between connection terminals due to whiskers even if whiskers grow from the connection terminals and a method for manufacturing an insert molded product. A cover body of a circuit board assembly has a plurality of partition walls that form a plurality of grooves each accommodating a corresponding one of connection terminals. The partition walls restrain the inner surface of a second cover of the cover body from entering the grooves when an external pressure is applied to a part of the cover body which covers the connection terminals. The partition walls also prevent contact between adjoining ones of the connection terminals when whiskers grow.

摘要： A sensor device includes a main driving gear, driven gears, an biasing member configured to bias the driven gears toward the main driving gear, a support member configured to support the biasing member, and a sensor configured to generate an electrical signal based on rotation of the driven gears. In a force applied when the biasing member biases the driven gears, assuming that a direction orthogonal to a tangent line at a point of action of the force is set as a first direction, the first direction is different from a second direction.

摘要： A sensor device includes a main driving gear, a driven gear, a biasing member, a support member, a rotational angle sensor, and a magnetic shield. The driven gear includes a gear portion and a shaft portion. The shaft portion is provided with a permanent magnet. The biasing member is configured to bias the driven gear toward the main driving gear. The support member supports the driven gear and the biasing member. The magnetic shield rotatably surrounds the shaft portion. The biasing member biases the driven gear toward the main driving gear by biasing the magnetic shield toward the main driving gear. The sliding resistance between the magnetic shield and the driven gear is lower than the sliding resistance between the magnetic shield and the biasing member.

The sensor assembly includes a magnetic sensor circuit, a holder holding the magnetic sensor circuit and including first and second holder members, and a resin case containing the holder. The magnetic sensor circuit is provided to output a detection value indicating a torque applied to the torsion bar and calculated from the magnetic flux output from the magnetic flux output device. The magnetic sensor circuit has first and second circuit principal surfaces. The magnetic sensor circuit is partially disposed in a space defined by the first and second holder members and a first holder side wall of the first holder member inclined inward and in contact with the second holder member.

摘要： A rotation angle detection device includes a correction-object driven gear that is a driven gear meshing with a main driving gear, a first sensor that is configured to generate an electrical signal based on rotation of the correction-object driven gear, and an electronic control unit that computes a driven-side rotation angle based on the electrical signal. The electronic control unit is configured to store a correction angle used to correct the driven-side rotation angle when computing the driven-side rotation angle. The correction angle is a predetermined deviation in a predetermined angle domain obtained as an average value in which deviations of the number equal to the integer and corresponding to a same relative rotation angle is averaged, so as to be deviation in an angle domain of 0 to 360 degrees.
