Sliding contact guide for transmission device

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 second 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 back surface opposite from said front guide surface and facing in said second direction, a pair of first ribs protruding from said back surface in said second direction, each of said first ribs being elongated in a direction substantially perpendicular to said first and second directions and said first ribs extending, along their directions of elongation, longitudinally along the shoe in spaced relationship to each other, and a lattice composed of second ribs disposed between the first ribs, each of said second ribs also being elongated in a direction substantially perpendicular to said first and second directions, and protruding from said back surface in said second direction, and the width of each of the first ribs, measured in a direction substantially perpendicular to said second direction and to the direction of its elongation, being greater than the widths width of each of said second ribs, also measured in a direction substantially perpendicular to said second direction and to its direction of elongation.
