A sensor attachment structure, comprising:

• an attachment partner comprising a cylindrical part, a flange provided at an end of the cylindrical part, a cutout formed in the flange, and a locking projection projecting from the flange on an opposite side to the cylindrical part;
• and
• a sensor comprising an insertion part inserted into the cylindrical part, an abutting part provided at one end of the insertion part integrally with the insertion part and abutting the flange when the insertion part is completely inserted into the cylindrical part, a locked part provided on the abutting part and locked with a locking projection, and a projection integrally provided on the insertion part, inserted into the cutout formed in the flange, clamping the flange together with the abutting part in an insertion direction of the insertion part, and clamping the flange together with the locked part in a direction crossing the insertion direction of the insertion part.
