<p>A rotation sensor includes a rotating body (2) that rotates together with a rotating shaft, an angle detector (3) that detects a rotation angle of the rotating body (2), and a casing (1) that accommodates the rotating body (2) and the angle detector (3). The casing (1) includes a lower casing member (10) having an open top and a tab portion (14) provided at the periphery of the lower casing member (10) and a cover member (11) that covers the top of the lower casing member (10). The tab portion (14) of the lower casing member (10) has a through hole (15) through which a metal collar (4) extends, the metal collar (4) having a shape that substantially matches the inner periphery of the through hole (15). The cover member (11) is made of metal and covers the top of the lower casing member (10) over a region including a top surface of the metal collar (4) that extends through the through hole (15).</p> |
