PROBLEM TO BE SOLVED: To provide an elastic body roller that is excellent in non-adhesiveness or detachability and further friction force (grip force) and can stably transport and guide belt-like members such as a label without a mount and a general label with a mount.SOLUTION: In the elastic body roller, it is notable that an outer layer of an inner layer-side elastic material 23 is coated with silicone resin (a coating layer 24) with C hardness (Spring type Asker C type hardness specified by the SRIS 0101 standard) set lower. An elastic member 22 of the elastic body roller has the inner layer-side elastic material 23 provided at an outer periphery of a roller shaft 21 and the coating layer 24 that is provided at an outer periphery of the inner layer-side elastic material 23 and contacts the belt-like members, and the coating layer 24 is constituted of silicone resin with C hardness of 20° or less. The inner layer-side elastic material 23 has tear strength of 25N/mm or more using a test piece with an angle shape without notch specified by the JISK 6252 standard. |
