In a sliding contact chain guide of the kind used in the timing transmission of an internal combustion engine, a synthetic resin guide shoe is attached to a pivoting support arm by protrusions formed as unitary parts of the shoe, which engage notches formed in the support arm. L-shaped protrusions formed on one side edge of the shoe engage both the back face and one side edge of the arm, and strip shaped protrusions on the opposite side edge of the shoe engage the opposite side edge of the arm. An L-shaped protrusion is formed adjacent one end of the shoe on the edge having the strip-shaped protrusions.
