The roller includes a cylindrical spindle and a cylindrical body, the ends of the spindle projecting from the lateral faces of the body. It is proposed that the support body includes supports open towards the opening of the sleeve and supporting the ends of the spindle. ## Claims ### Claim 1 A cam follower roller device comprising: a tappet (10) having a sleeve (12) including an opening adapted to partially accommodate a roller (14); a roller (14) rotatably mounted to the sleeve (12) and having a portion which protrudes axially from the opening of the sleeve (12) to cooperate with a cam, the roller (14) including a spindle (16) and a cylindrical body (18), ends of the spindle (16) projecting from the lateral faces of the body; a support body (22) for the roller (14) housed in the sleeve (12); and the support body (22) including supports (20a, 20b) which support the ends of the spindle (16). ### Claim 2 (depends on 1) The cam follower roller device according to claim 1, wherein the supports (20a, 20b) are open towards the opening of the sleeve (12). ### Claim 3 (depends on 2) The cam follower roller device according to claim 2, further comprising a retaining means (28) for holding the roller (14) in the sleeve (12) during transportation. ### Claim 4 (depends on 3) The cam follower roller device according to claim 3, wherein the retaining means (28) is implemented by a deformation of the edge of the opening of the sleeve (12) produced after the support body (22) and the roller (14) have been inserted. ### Claim 5 (depends on 4) The cam follower roller device according to claim 4, wherein the support body (22) is seated on a base (24) of the sleeve (12). ### Claim 6 (depends on 5) The cam follower roller device according to claim 5, wherein the base of the sleeve (24) is fixed in the sleeve (12) by a press fit. ### Claim 7 (depends on 6) The cam follower roller device according to claim 6, wherein the base of the sleeve (24) is fixed in the sleeve (12) by a press fit in combination with external deformation of the sleeve (12). ### Claim 8 (depends on 7) The cam follower roller device according to claim 7, wherein the support body (22) is produced from a strip of sheet metal cut and bent to form a ring shape. ### Claim 9 (depends on 8) The cam follower roller device according to claim 8, wherein the support body (22) includes a structure or slit interacting with a corresponding structure of the sleeve (12) so as to provide an anti-rotation function. ### Claim 10 (depends on 6) The cam follower roller device according to claim 6, wherein the support body (22) is a ring of plastics material with metal supports (20a, 20b) inserted or moulded into the plastics material. ### Claim 11 A method of manufacturing a cam follower roller device comprising the steps of: providing a tappet (10) having a sleeve (12) including an opening adapted to partially accommodate a roller (14), a roller (14) rotatably mounted to the sleeve (12) and having a portion which protrudes axially from the opening of the sleeve (12) to cooperate with a cam, the roller (14) including a spindle (16) and a cylindrical body (18), ends of the spindle (16) projecting from the lateral faces of the body, a support body (22) for the roller (14) housed in the sleeve (12), and the support body (22) including supports (20a, 20b) which support the ends of the spindle (16), inserting the support body (22) into the sleeve (12), and inserting the roller 14 into the sleeve 12.
