An embodiment relates to a sensing device comprising: a rotor; and a stator arranged on the outer side of the rotor, wherein the stator comprises a stator holder and a stator ring arranged on the stator holder; the stator ring comprises a body, a plurality of teeth formed to protrude from the inner peripheral surface of the body, and a protrusion portion formed to protrude from the outer peripheral surface of the body; and, when seen in the radial direction, the protrusion portion is arranged between the teeth and comprises at least two protrusions arranged to be spaced from each other. Accordingly, the coupling force between the stator holder and the stator ring can be improved.
