To provide an overhead carrier capable of surely realizing enabling of vibration control in traveling and transfer stabilization in transferring.SOLUTION: An overhead carrier 1 includes a traveling unit 3 traveling along a track 100, a holding unit 7 having a holding part 70 for holding a FOUP 200, an elevation driving unit 6 having an elevation driving part 60 for moving up/down the holding unit 7, a switching mechanism 9 making the holding part 70 in a floating state when the holding unit 7 is positioned at a rising end and making the holding part 70 in a lock state when the holding unit 7 is positioned lower than the rising end, and an elastic member 11 supporting the holding part 70 kept in a floating state. The switching mechanism 9 makes the holding part 70 in the floating state or the lock state in linkage with an elevation movement of the holding unit 7.SELECTED DRAWING: Figure 3

    【課題】走行時における防振の有効化及び移載時における移載の安定化を確実に実現することができる天井搬送車を提供する。【解決手段】天井搬送車1は、軌道100に沿って走行する走行ユニット3と、FOUP200を保持する保持部70を有する保持ユニット7と、保持ユニット7を昇降させる昇降駆動部60を有する昇降駆動ユニット6と、保持ユニット7が上昇端に位置する際に保持部70をフローティング状態にし、保持ユニット7が上昇端よりも下側に位置する際に保持部70をロック状態にする切替機構9と、フローティング状態にある保持部70を支持する弾性部材11と、を備える。切替機構9は、保持ユニット7が昇降する動作に連動して保持部70をフローティング状態又はロック状態にする。【選択図】図3
