The present invention relates to a track bush for a crawler track, more specifically, which forms a tapered shape on an end portion of an inner circumferential surface, and forms curvature on a boundary point between the inner circumferential surface and the tapered shape. Therefore, the track bush is pressed in a link to be assembled for a protruding portion not to be formed on the inner circumferential surface of the track bush. Moreover, as the track bush and a track pin are assembled, when a crawler track is driven, stress between the track bush and the track pin is not concentrated on a specific portion to be dispersed, thereby reducing wear of the track bush. |
