PURPOSE: An angle control device for a conveyor is provided to firmly keep the angle adjusted position without a position fixing unit. CONSTITUTION: A wheel supporter with wheels on the bottom is installed to be foldable on a conveyor. A wire reel unit includes a winding drum(140) in which the wire connected to the wheel supporter is reeled, and a movable gear(130) whose rotation is limited by a rotation prevention plate(150). In the inner side of one end of the winding drum, a fixed gear(142) is arranged. The movable gear engages with the fixed gear by idling through an eccentric cam(122) and transmits the torque of a handle(H).
