An article transport vehicle that travels along a traveling path is provided with an obstacle sensor that detects an obstacle that exists in a detection area, and a control unit that controls the traveling speed of the article transport vehicle based on detection information of the obstacle sensor. A non-detection area where detection of the obstacle by the obstacle sensor is not performed is set within the detectable area of the obstacle sensor, and a situation in which the non-detection area exists on a detection line that joins a part of the detection area and the obstacle sensor is defined as a specific situation. The control unit, in the specific situation, and a situation where an undetectable area in which it is not possible to detect the obstacle exists in the detection area because a shield exists in the non-detection area, reduces the speed of the article transport vehicle to a second traveling speed slower than the first traveling speed.

Article transport facility

A fire door includes: an outer frame; a door body; and a center rail, the center rail is provided so as to overlap a target area in a wall orthogonal direction view, and so as to extend in a width direction between a first frame portion and a second frame portion on the side opposite to the wall body with respect to the target area, the center rail and the first frame portion are fixed to each other, the center rail and the second frame portion are engaged with each other with an engaging mechanism interposed therebetween, and the engaging mechanism is configured to allow relative movement of the center rail relative to the second frame portion in the width direction, and to regulate the relative movement thereof in the wall orthogonal direction and a slide direction.

Fire door

A sliding fire door is disclosed with an improved tightness of the closure by the door main body. The sliding fire door includes an opening frame, a fire door, and a guiding mechanism. The guiding mechanism includes a guide roller group which includes a plurality of guide rollers arranged one adjacent to another along the slide direction and which is configured to guide the door main body. The guiding mechanism is configured to guide the door main body such that the door main body is moved from an opening position to a closing position. The door main body has a first opposing surface which is oriented toward the wall. The opening frame has a second opposing surface which is oriented toward the first opposing surface of the door main body in the closing position. The guiding mechanism moves the door main body to cause the first opposing surface to be moved closer to the second opposing surface when the door main body is moved from the opening position to the closing position.

Sliding fire door

A support member includes a first positioning portion for properly positioning a small container, and a second positioning portion for properly positioning a large container. The first positioning portion includes one or more first support members for supporting the small container, and first engaging members for engaging first engaged portions. The second positioning portion includes one or more second support members for supporting the large container at a height at which the bottom surface of the large container is located at a higher position than the upper ends of the first engaging members, a second engaging member provided outside the first supporting area for engaging a second engaged portion, and one or more contact members provided outside the first supporting area for contacting the large container from one or more sides.
