PROBLEM TO BE SOLVED: To provide a work pallet positioning fixing device which is capable of positioning in the horizontal and the vertical two directions via elastic deformation of an annular engaging part, of elastically deforming the engaging part over the whole circumference and of surely elastically deforming even at a local part in the circumferential direction, etc. SOLUTION: When the work pallet 1 is positioned and fixed to a base body 2 by the positioning fixing device 3, the work pallet 1 can be positioned to the base body 2 in the horizontal and the vertical directions with high accuracy, and moreover, positioning accuracy is not reduced by cutting chips or the like since elastic deformation of the engaging part 66 integrally formed to a bush 60 in the diameter enlarging direction is allowed by an annular relieving groove 68 and a plurality of slits 70 are formed to the engaging part, and the engaging part 66 easily deforms elastically in the diameter enlarging direction and a state that an annular tapered face 67 of the engaging part 66 is adhesively engaged with the annular tapered face 23 of a cylindrical axis part 10b is maintained.
