    • A detection device and a rotation angle sensor reduce the bending stress of a substrate, avoid breaking, peeling, and soldering cracks of patterns, and provide high reliability and low production cost. A detection device includes an outer case defined by a case body and a cover member. A support portion in the case body is provided with fitting protuberances that are fitted in fitting holes of a printed board, on which a detection component is mounted, so as to position the printed board. Each protuberance has ribs protruding from an outer peripheral surface thereof. The ribs are elastically or plastically deformed by contact with an inner peripheral surface of the corresponding fitting hole of the printed board, and position the board along a support surface of the support portion. A projecting portion of the cover member is elastically or plastically deformed so as to urge the board toward the support surface of the support portion so that the board is clamped between the projecting portion and the support surface and is positioned in a direction perpendicular to the support surface of the support portion.
    • 检测装置和旋转角度传感器降低基板的弯曲应力,避免图案的断裂,剥离和焊接裂纹,并提供高可靠性和低生产成本。 检测装置包括由壳体和盖构件限定的外壳。 壳体中的支撑部分设置有安装在其上安装有检测部件的印刷电路板的安装孔中的配合突起,以便定位印刷电路板。 每个突起具有从其外周表面突出的肋。 肋通过与印刷板的相应装配孔的内周表面接触而弹性或塑性变形,并且沿着支撑部分的支撑表面定位该板。 盖构件的突出部分弹性或塑性变形,以将板推向支撑部分的支撑表面,使得板被夹持在突出部分和支撑表面之间并且被定位在垂直于支撑件的方向上 支撑部分的表面。
