PROBLEM TO BE SOLVED: To provide a conical roller installation device for eliminating a roller slip-off product, by supplying a conical roller, without using a free fall of the conical roller.SOLUTION: The conical roller installation device comprises a feed shaft 2 provided with a projection strip 3 continuing in a spiral shape. The spiral projection strip 3 has a thick projection strip 12 formed so as to gradually increase in width in the axial direction by continuing with the lower end of a thin projection strip 11. A conical roller 52A positioned in a lower end part in a roller passage 10, is sent up to a pocket corresponding position before the feed shaft 2 rotates one revolution by pushing an upper surface to an under surface of the thick projection strip 12. A roller pushing-in tool 6 comprises a taking-out part 13 for moving the conical roller 52A up to the pocket corresponding position by supporting the under surface of the conical roller 52A positioned in a lower end part in the roller passage 10, and a pushing-in part 14 fitted in a pocket 51a by pressing the conical roller 52A moved up to the pocket corresponding position to move it outward in the radial direction. |
