1 ...4 4 is a feed roller, and this feed roller has a shaft 3 with a larger diameter than the support shafts 2, 2 formed with a pair of support shafts 2, 2 protruding from both ends. The outside is integrally covered with a cylindrical roller portion 4 made of a highly elastic material such as rubber or polyurethane, similar to known rollers. Reference numerals 5 and 5 designate a pair of shaft bearings, each of which is made of a material such as plastic, and has a disc-shaped portion that engages with the outer surface 6' of the stepped portion 6 formed at both ends of the shaft 3. 7, and a substantially oval-shaped part extending outward from the disc-shaped part 7 and projecting outward, and having a length l shorter than the length L of the diameter of the disc-shaped part 7. It consists of a protrusion 8 for engagement having a length of With the respective protrusions 8 positioned outward, the respective shaft holes 9 are inserted into the support shaft 2, and one side 7' of the respective disk-shaped portions 7 are connected to the support shaft 2 with the respective disks. The shaped portion 7 is inserted until one side surface 7' of the stepped portion 6 of the shaft 3 engages with the outer surface 6' of the stepped portion 6, and is suspended so that they can rotate relative to each other.
Reference numeral 10 denotes a support plate made of sheet metal with a substantially arc-shaped cross section, and this support plate has elongated holes 11, 1 for mounting the feed rollers 1, 1 1 ... 1 4 .
1 1 ... 11 4 are drilled, and each long hole 11
On both sides of the feed rollers 1, 1 1 ... 1 4
The upper part that engages with the protrusion 8 of the bearing 5 mounted on the bearing shaft 2 at both ends of the shaft is open, and the depth thereof is
A pair of ears 13, 13 each having a notch 12 whose l' is shorter than the length L of the diameter of the disk-shaped portion 7 is provided to protrude downward.

しての機能を充分に果せることゝなる。 Since the present invention has the above-mentioned configuration, in order to install the feed rollers 1, 1 1 ... 1 4 on the support plate 10, the feed roller 1 must be mounted on the support plate 10.
is inserted into the elongated hole 11 from above, and the protrusion 8 of the shaft support 5, which is placed on the support shaft 2 at both ends thereof, is inserted into the notch 12 of the ear part 13 from above.
It is only necessary to fit the cutout 12 until its lower side 8' abuts against and is received by the bottom 12' of the notch 12. (FIGS. 1 and 3 show this state.) In this state, both side surfaces 14, 14' of the protrusion 8 are engaged with both inner surfaces 15, 15' of the notch 12. In addition to the fact that the bearing 5 does not rotate, the length l of the protrusion 8 is shorter than the length L of the diameter of the disc-shaped part 7 as described above, so that the roller part 4 is located above the surface of the support plate 10. The feed roller 1 is supported by a support device so that it can rotate freely in the protruding state, so that it can fully perform its function as a feed roller.

極めて多大である。 As mentioned above, in this case, the feed roller 1 is inserted into the long hole 11 of the support plate 10 from above, and the protrusion 8 of the bearing 5, which is placed on the support shaft 2 at both ends of the feed roller 1, is inserted into the support plate 10. The feed roller 1 can be attached to the support plate 10 by an extremely simple operation of fitting it into the notch 12 of the ear portion 13 of the feed roller 1, and it can be removed from the support plate 10 for repairs etc. Not only can the feed roller 1 and the bearing 5 be pulled upward from the lug 13 of the support plate 10, but also the support plate 10, its elongated hole 11, lug 13, etc. can be pressed, and the bearing 5 can be Not only can they be manufactured extremely easily by molding plastics, etc., but also the shaft bearings 5
is made of materials such as plastic,
In addition to allowing the feed roller 1 to rotate smoothly, there is little wear between the bearing shaft 2 and the shaft hole 9 of the bearing 5, and it can be used for many years, so the practical effects of its use are extremely large. .
