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： 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.

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 where the number of components and mounting steps can be reduced and mountability on a mounting target is improved. A sensor device configured to detect a torque applied to a pinion shaft and pinion shaft's rotation angle. The pinion shaft is formed by coupling an input shaft and output shaft together by a torsion bar. The sensor device includes a torque detecting portion wherein magnetic fields detected by torque detection magnetic sensors change based on the torsion bar's twisting amount, a rotation angle detecting portion wherein magnetic fields detected by rotation angle detection magnetic sensors change based on the pinion shaft's rotation angle, a housing that houses the torque detecting portion and the rotation angle detecting portion, and a circuit board held by the housing. Both the torque detection magnetic sensors and the rotation angle detection magnetic sensors are mounted on the circuit board.
