To provide an electric assist carriage that is configured to prevent a driving wheel from being driven when applying pressing force or tensile force only to an either handle.SOLUTION: An electric assist carriage 10 according to the present invention comprises: driving wheels 24L and 24R arranged at left and right sides of a base; driving mechanisms 26L and 26R that rotationally drive the driving wheels respectively; a left handle 20L arranged behind the base; and a right handle 20R, which further comprises: left pressing force detecting means 23L, arranged in the left handle, which detects pressing force acting on the left handle; right pressing force detecting means 23R, arranged in the right handle, which detects pressing force acting on the right handle; and control means 30. The control means does not allow the left driving mechanism and the right driving mechanism to rotationally drive the wheels, when an absolute value of pressing force detected by one of the left pressing force detecting means and the right pressing force detecting means is over a predetermined threshold but an absolute value of pressing force detected by the other is below the predetermined threshold.SELECTED DRAWING: Figure 10
【課題】本発明は、一方のハンドルのみに押力又は引張力を加えたときに駆動輪が駆動しない電動アシスト台車を提供する。【解決手段】本発明に係る電動アシスト台車10は、基台の左右に配置される駆動輪24L,24Rと、各駆動輪を回転駆動する駆動機構26L,26Rと、前記基台の後方に配置される左ハンドル20Lと、右ハンドル20Rと、を具え、前記左ハンドルに配備され、前記左ハンドルに作用する押圧力を検知する左押圧力検出手段23Lと、前記右ハンドルに配備され、前記右ハンドルに作用する押圧力を検知する右押圧力検出手段23Rと、制御手段30と、を具える電動アシスト台車であって、前記制御手段は、前記左押圧力検出手段又は前記右押圧力検出手段の一方で検出される押圧力の絶対値が所定の閾値を超えるが、他方で検出される押圧力の絶対値が所定の閾値以下の場合、前記左駆動機構及び前記右駆動機構を回転駆動しない。【選択図】図10
