In a sliding contact chain guide of the kind used in the timing transmission of an internal combustion engine, the back of the guide shoe, which engages a metal guide base, is formed with two, spaced longitudinal ribs, having between them a set of ribs formed in a lattice. The longitudinal ribs are wider than the ribs of the lattice.
Claims3
A sliding contact guide comprising a metal guide base, and an elongated resin shoe fixed to said guide base, said shoe having a front guide surface, facing in a first direction, for sliding contact with a flexible transmission medium traveling along the direction of elongation of the shoe, a back facing in a direction opposite to said first direction, in abutting relationship with said guide base, and a pair of opposite sides, the front guide surface, and the back both being situated between said opposite sides, wherein said back comprises a pair of elongated first ribs extending longitudinally along the shoe in spaced relationship to each other, and a lattice composed of elongated second ribs disposed between the first ribs, the widths of the first ribs, measured in directions perpendicular to the direction in which said back faces, being greater than the widths of said second ribs, also measured in directions perpendicular to the direction in which said back faces.
