A boom lodging movement limiting device for a work vehicle, particularly an aerial work vehicle configured to drive and operate a swivel platform and a boom on a bucket, wherein when the boom is driven to lie down, this boom touches a part of the vehicle or the vehicle. Dangerous turning area detection means that detects and activates a turning area of the swivel base that poses a risk of destroying the installed structure as a dangerous turning area, and when a boom is driven to fall down in the dangerous turning area, the boom is activated to lower the vehicle. Lodging area detection means that detects and activates a boom lodging area where there is a risk of destroying a part or a structure installed on the vehicle as a dangerous lodging area, and operating a hoisting operation lever of the boom hoisting drive device in the boom lodging direction. a lodging operation detection means that operates in conjunction with the operation when the boom is activated; and a stopping means associated with the hoisting drive device so as to stop at least the lodging motion of the boom when the boom is activated, and the dangerous turning area detection means , wherein each of the detection means and the stop means are connected in relation to each other by an electric circuit so that the stop means is activated when both the lodging area detection means and the lodging operation detection means are activated. Boom lodging motion restriction device.
