PROBLEM TO BE SOLVED: To provide detection means which solves, by a simple configuration, the problem of inability to calculating a rotational angle in the horizontal direction and a deflection angle (inclination).SOLUTION: The present invention includes: a magnetic sensor having a bridge circuit outputting a voltage value according to the direction of an input magnetic field; a magnet with an S-pole and an N-pole facing a magnetic field detection surface of the magnetic sensor; and angle calculation means for calculating a rotational angle of the magnet around the axis in the vertical direction to the magnetic field detection surface of the magnetic sensor based on the voltage value output from the magnetic sensor and calculating the angle of the inclination of the magnet to the magnetic field detection surface based on a predetermined reference value and the voltage value output from the magnetic sensor.SELECTED DRAWING: Figure 1 【課題】簡易な構造で、水平方向の回転角を算出するとともに偏向角度（傾き）を算出することが不可能である、という問題を解決することが出来る検出手段を提供すること。【解決手段】入力される磁界の向きに応じて電圧値を出力するブリッジ回路を含む磁気センサと、Ｓ極とＮ極とが前記磁気センサの磁界検出面と対面するよう配置された磁石と、前記磁気センサが出力した電圧値に基づいて、前記磁気センサの磁界検出面に対する垂直方向の軸を中心とした前記磁石の回転角度を算出するとともに、予め定められた基準値と前記磁気センサが出力した電圧値とに基づいて、前記磁界検出面に対する前記磁石の傾きの角度を算出する角度算出手段と、を有する。【選択図】図１
