PROBLEM TO BE SOLVED: To provide an elastic body roller which has excellent non-adhesiveness or detachability, a friction force (grip force) and abrasion resistance, and can stably transfer and guide a band-like member such as a label without a mount and a general label with a mount.SOLUTION: The elastic body roller has an inner layer side elastic material 23 on the outer periphery of a roller shaft 21, and a coating layer 24 which comes in contact with a band-like member on the outer periphery of the inner layer side elastic material 23. The coating layer 24 is formed from a silicone resin having a C hardness of 20 degrees or less. A base layer 23a and an intermediate layer 23b of the inner layer side elastic material 23 have A hardness of 30-80 degrees. A rubber hardness of the base layer 23a is higher than the rubber hardness of the intermediate layer 23b. The intermediate layer 23b has a tear strength using a notched angular test piece specified by JIS K 6252 standard of 25 N/mm or more, and an inner layer groove 31 thereof has a V-shaped cross section and a groove angle of 40-160 degrees.SELECTED DRAWING: Figure 1 |
