摘要

In a crawler type traveling apparatus so arranged on each side of a vehicle as to be capable of rocking up and down through each pivot shaft and including a track frame rocking round the pivot shaft, and a final reduction gear inclusive of a sprocket and a hydraulic motor that are provided at an end part of the track frame, the invention provides a crawler type traveling apparatus for achieving a compact and economical piping construction and high reliability. A hydraulic motor is provided on a vehicle inner side with respect to a final reduction gear. Hydraulic passages communicating with the hydraulic motor are formed in a pivot shaft. Ports for connecting respectively a predetermined number of hydraulic piping arrangements connected to the hydraulic motor and the like are formed in an outer peripheral surface of the pivot shaft.
