Abstract: An overhead conveying vehicle is arranged to contain and convey a suspended FOUP including a lid that is removably provided on a side surface thereof. The overhead conveying vehicle includes a conveying vehicle body, a hoist mechanism, a lid drop preventing member, and a power transmitting mechanism. The hoist mechanism is provided at the conveying vehicle body and is arranged to raise and lower the FOUP. The lid drop preventing member is arranged in close proximity to a front surface of the lid. The power transmitting mechanism retracts the lid drop preventing member away from the front surface of the lid when the FOUP is being raised or lowered.
