ELASTIC ROLLER

Provided is an elastic roller that is capable of elastic deformation at low load, that is lightweight and low-cost, and that is such that the surface speed of the roller has been made stable. At a drawing showing the view from the side of pipe 2 and flange 3 which make up roller 1, roller 1 in accordance with the present invention which has pipe 2 and flange 3 is supported by shaft 8 which is inserted therein along axis 8a of shaft 8, the situation being such that elastic deformation occurs upon being pressed downward by pressure P from pressure-applying body 11 above pipe 2. (a) inFIG. 6is a drawing in which none of the four outermost ribs 7a disposed in outermost gap 6a between outermost ring 4a of flange 3 and middle ring 4b which is mutually adjacent thereto and toward the interior therefrom is present in the upper portion of pipe 2, being a drawing in which this is pressed downward by pressure P from pressure-applying body 11 above thin-walled cylindrical pipe 2a directly above a location in outside gap 6a which is intermediate between two mutually adjacent ribs 7a that are separated from each other so as to be disposed at left and right at outside gap 6a, and in which outermost ring 4a and thin-walled cylindrical pipe 2a at that location press upward in resilient fashion, and are indented therebelow by amount of indentation 12.
