Anti-vibration rubber member and production method thereof

A production method of an anti-vibration rubber member that absorbs at least a portion of vibration of a mating member and has a sliding surface that is relatively in sliding contact with the mating member, the production method of an anti-vibration rubber member characterized by comprising the steps of:

• creating a rubber elastic body that is made of a self-lubricating rubber containing an elastomer and a bleeding lubricant through a cross-linking reaction;
• degreasing a sliding inner surface that is among a surface of the rubber elastic body and disposed on an inner side of the sliding surface;
• coating on the sliding inner surface after degreasing a coating that contains a thermosetting resin having at least one type of functional group selected from a mercapto group, a vinyl group, an epoxy group, a methacryloxy group, and an amino group, and a minute hole forming agent that is released when baked to form minute holes in a coating film;
• and
• baking the rubber elastic body coated with the coating such that a coating film is formed on the sliding inner surface while the minute hole forming agent is released from the coating, and the bleeding lubricant of the rubber elastic body penetrates the coating film and oozes onto a surface of the coating film to form a lubricating film including the bleeding lubricant on the surface of the coating film.
