Claim 44:
45. A method for mounting a stroke sensor module on a support having a through-hole and a positioning portion, wherein the stroke sensor module comprises:
a moving element that is moved in a first direction;
a magnetic field generator that is moved in the first direction together with the moving element;
a magnetic field detecting element that detects movement of the magnetic field generator; and
a housing that houses a part of the moving element and the magnetic field generator, wherein
at least either the moving element or the magnetic field generator has a plurality of protrusions that are provided at different angular positions, as viewed in the first direction,
the housing has guide portions that guide the protrusions,
the housing has an inserted portion that is inserted into the through-hole, a mounting portion that is fixed to a mounting surface of the support, and engaging portion that engages the positioning portion so as to position the housing in the first direction, and
the mounting portion and the engaging portion are positioned at different angular positions, as viewed in the first direction,
the method comprises the steps of:
inserting the inserted portion of the housing into the through-hole, and rotating the housing about a central axis of the through-hole, thereby engaging the engaging portion with the positioning portion so as to position the housing in the first direction; and
