Abstract:
1. A guide for a transmission device comprising: an elongated shoe having a front surface, facing in a first direction, for sliding contact with an endless, flexible, transmission medium traveling along the direction of elongation of the shoe, said shoe having a back surface facing in a second direction opposite to said first direction, first and second opposite ends spaced from each other along the direction of elongation of the shoe, and opposite side edges extending in the direction of elongation of the shoe; an elongated base frame mountable on a mounting surface, said base frame extending along the back surface of the shoe and supporting said shoe, and having first and second elongated sides; a plurality of L-shaped engagement portions and strip shaped engagement portion, said engagement portions being integrally molded as a unit with said shoe and protruding from the back surface of the shoe along said side edges in an alternating arrangement in which, proceeding from one end of the shoe to the other, each successive engagement portion is farther from said one end, and protrudes from a different side edge than, an immediately preceding engagement portion, whereby said engagement portions alternately embrace the first and second elongated sides of said base frame; wherein each said L-shaped engagement portion comprising a first leg extending in said second direction past a side of the base frame, a second leg extending laterally in a direction such that a part of the base frame is located between the second leg and the back surface of the shoe, and a positioning tongue extending obliquely, from within a cut-out in said first leg, toward, and resiliently pressing against, an adjacent side of the base frame; and wherein each said strip-shaped engagement portion includes a frame positioning limiting surface, extending obliquely from the back surface of the shoe toward, and resiliently pressing against, an adjacent side surface of the base frame.
