摘要： In order to suppress the collection of articles that are different from those specified when collecting articles using an article transport vehicle from a plurality of accommodating portions that accommodate articles, an article transport vehicle (3) includes a control portion (15), and a weight detecting portion (18) that detects a total weight (W) of articles (B) supported by a support portion (12), wherein articles picked up from accommodating portions (1) are supported by the support portion (12). In a case in which an increased weight (ΔW), which is an increase in the total weight (W) when an article (B) is newly supported by the support portion (12), is out of a prescribed range (WL, WH) according to a weight (BW) of a target article, which is an article (B) that is to be picked up from the accommodating portion (1), the control portion (15) determines that the target article was not correctly picked up, and makes a notification giving error information.

摘要： A placement body on which an article is placed is driven by a transfer drive mechanism to transfer the article. The transfer drive mechanism includes a transfer drive source and a transmission mechanism. The transmission mechanism includes an output member coupled to an output shaft of the transfer drive source and a driven member that is not coupled to the output member and operates by being pressed by the output member. A wheel drive source, the transfer drive source, and the output member are supported by a vehicle body frame, and the placement body and the driven member are supported by a vehicle body cover. The vehicle body cover covers the wheel drive source and the transfer drive source and is detachably attached to the vehicle body frame.
