A transport trolley and a walker that make an inclination angle of the transport trolley small while preventing a stopper member from colliding with an obstacle. The transport trolley is provided with a traveling trolley main body provided with multiple wheels, a stopper member that restricts inclination of the trolley main body by contacting a floor surface in a case in which the trolley main body is inclined to one side in the travel direction, and an elastic member that applies elastic force such that the stopper member returns to an initial angle. The stopper member, when contacting an obstacle from the front or rear in the travel direction, avoids the obstacle by rotating in the rotation axis line against elastic force due to the load in the travel direction received from the obstacle.
