To provide a crawler drive unit which enables reduction of a possibility that a motor contacts with sand or rocks etc., and to provide a construction machine.SOLUTION: A crawler drive unit 1 of an embodiment includes: a speed reduction mechanism 4 which is provided at a travel part 102 which causes a vehicle main body 101 to travel and transmits driving force to a crawler provided at the travel part 102; a transmission mechanism 3 which transmits the driving force to the speed reduction mechanism 4; and an electric motor 2 which applies rotational force to the speed reduction mechanism 4. A motor shaft 7 of the electric motor 2 is located above a rotation axis Jn of an input shaft 16 of the speed reduction mechanism 4.SELECTED DRAWING: Figure 2

    【課題】土砂や岩等にモータが接触してしまう可能性を低減できるクローラ駆動ユニット及び建設機械を提供する。【解決手段】実施形態のクローラ駆動ユニット1は、車体本体101を走行させる走行部102に設けられ、走行部102に設けられたクローラに駆動力を伝達する減速機構4と、減速機構4に駆動力を伝達する伝達機構3と、減速機構4に回転力を付与する電動モータ2と、を備える。電動モータ2のモータシャフト7は、減速機構4の入力シャフト16の回転軸線Jnよりも上方に位置している。【選択図】図2
