PROBLEM TO BE SOLVED: To provide a rubber part for iron track shoes improved in durability by suppressing the deformation of a protrusive member vulcanized and bonded to the outer circumference of a pipe due to a compression and torsion load applied on the protrusive member, and preventing the protrusive member from being broken away from the pipe. SOLUTION: The rubber part is constituted of the metal pipe 12 provided with a connection pin insertion hole 13 in an inner peripheral surface and a plurality of protrusive rubber members 11, and the protrusive rubber members 11 are vulcanized and bonded on the outer peripheral surface of the pipe 12 like a rib in the longitudinal direction of the pipe 12.
