ABSTRACT:
A crawler belt drive apparatus which can reduce meshing noises of drive sprocket and crawler belt in a reliable manner over a long period of time. An annular link guide member is provided on a housing of a reducer concentrically with the drive sprocket. As bushes of the respective track links of the crawler belt are meshed with the drive sprocket, the link guide member is held in sliding contact with inner end faces of the track links to maintain a clearance constantly between each bush and a bottom of the drive sprocket, thereby preventing the bushes from directly hitting against the bottom of the drive sprocket to suppress meshing noises or vibrations effectively.
