To enable an equipment to surely detect a vehicle in an opened work passage, in the storage conveying equipment utilizing a storage device utilizing a moving rack so as to form the work passage between mutually adjacent racks by cross moving a cross movable rack and an in/out stock use transport vehicle of forklift or the like able to advance in the work passage.

An obstacle detector 6a to 6c, formed by parallelly providing an optical obstacle detection sensor (projector side unit 7 and light receiver side unit 8) with an optical axis 27a penetrating a space in a bottom part of a moving rack 3 to 5 in a moving rack cross moving direction so as to arrange in parallel the optical axis 27a with an equal space apart in a depth direction of a work passage A to D, is arranged in a total region in a depth direction of the work passage A to D, in an in/out stock use transport vehicle 40, a detected use shield bodies 43, 44 with a lower end lower than an on-floor surface optical axis height of the sensor and a width wider than optical axis space of the sensor is mounted.
