ABSTRACT:
A track guiding guard for a crawler type vehicle which is mounted along the lower side of a track frame is disclosed. The track guiding guard comprises a pair of left and right guard members which rotatably support track rollers. Each guard member has a slanted bottom surface which defines a limit angle of inclination between the same and the upper surfaces of track shoes that face the bottom surface, the angle diverging laterally outward. Each guard member further defines a predetermined gap between the inner side surface of the lower end thereof and the outer ends of track pins that face the inner side surface. The gap is so set that when the bottom surface of the guard member is seated on the upper surfaces of the track shoes, the inner side surface of the lower end of the guard member substantially comes into contact with the outer ends of the track pins. Thus, the inclination of the vehicle is stably supported by the seating of the bottom surface of the guard member on the upper surfaces of the track shoes and the contact between the inner surface of the lower end of the guard member and the outer ends of the track pins.
