A toothed belt adapted to be used while wet with a mineral oil has a ring of elastomeric material for a body, a tension resistant member inserted in the body, teeth on at least one side of the body, a rigid covering which is substantially non-deformable under flexion stresses for the teeth and intermediate groove surfaces made by doubling a rubberized fabric over an elastomeric layer as described in U.S. Pat. No. 3,937,094. The body, the teeth and rubberized fabric are all made from an oil resistant elastomer such as an epichlorohydrin rubber composition.
