Abstract:
1. A proximity sensor, comprising: a fixing member; and a proximity sensor body; wherein the proximity sensor is mounted on a mount, the mount having an elongated cylindrical hollow having a longitudinally-extending opening that is narrower than a diameter of the hollow and which is transversely connected with the hollow, wherein the proximity sensor body is housed in the hollow and fixed with the fixing member, the proximity sensor body comprising an elongated body having a first fixed area formed on an upper side facing the opening, a detection face provided on an opposing lower side facing a bottom surface of the hollow, and a housing hole extending between the detection face and the first fixed area, wherein a cross-sectional width of the proximity sensor body between the first fixed area and the detection face is narrower than the opening to enable the proximity sensor body to be transversely inserted into the hollow through the opening, the fixing member having: a securing portion provided between the first fixed area and a second fixed area disposed on an interior surface of the hollow adjacent the opening, the second fixed area facing opposite to and being spaced apart from the first fixed area; an axis portion that protrudes from the securing portion along a rotational axis that penetrates the opening, wherein the axis portion is housed in the hole of the proximity sensor body in a rotatable state, wherein the securing portion is formed in a shape rotatable around the rotational axis, the securing portion having a wide width portion where a distance between opposed positions on the wide width portion in a plane orthogonal to the rotational axis is wider than the opening, and a narrow width portion where a distance between opposed positions on the narrow width portion in a plane orthogonal to the rotational axis is narrower than the opening to enable the securing portion to be transversely inserted into the hollow through the opening; and having a first abutting portion abutting on the first fixed area and a plurality of second abutting portions formed on the wide width portion and abutting on an adjacency of the opening of the second fixed area, each of the plurality of second abutting portions having an inclined guide face that inclines in a circumferential direction with one rotational directional coming closer to the opening and that inclines in a radial direction with a position closer to the rotational axis coming closer to the opening, and wherein each of the inclined guide faces is made to abut on the second fixed area, with the first abutting portion abutting on the first fixed area.
