CONVEYANCE DEVICE

To suppress increases in manufacturing cost and maintenance cost and to provide a structure suitable for miniaturization and lowering floor in a conveyance device which holds and conveys a load and can adjust pressure of a driving wheel to a road surface according to the presence or absence of the load.SOLUTION: A conveyance device 1 at least includes: a body section which has a driving wheel 4; and a load holding section 3 which holds a load W. The body section 2 has a suspension section 6 which suspends the driving wheel 4 from a base body 2A of the body section 2, an energization member 7 which gives energization force with respect to a travel surface G to the driving wheel 4 through the suspension section 6, and an energization force adjustment section 8 which adjusts the energization force by pressing the energization member 7. A displacement operation section 9 is provided to cause the load holding section 3 to perform a displacement operation to a holding state A in which the load holding section 3 holds the load W and a non-holding state in which the load holding section 3 does not hold the load W. An energization force adjustment section 8 adjusts the energization force by interlocking with the displacement operation of the load holding section 3.SELECTED DRAWING: Figure 8 【課題】荷を保持して搬送する、荷の有無に応じて駆動輪の路面に対する圧力を調整できる搬送装置において、製造コスト及び保守コストの増大を抑制するとともに、小形化及び低床化に適した構造にする。【解決手段】少なくとも、駆動輪４を備える本体部と、荷Ｗを保持する荷保持部３とからなる搬送装置１である。本体部２は、駆動輪４を本体部２の基体２Ａに懸架する懸架部６と、走行面Ｇに対する付勢力を、懸架部６を介して駆動輪４に与える付勢部材７と、付勢部材７を押圧することで、前記付勢力を調整する付勢力調整部８とを備える。荷保持部３が荷Ｗを保持している保持状態Ａと、荷保持部３が荷Ｗを保持していない非保持状態とに荷保持部３を変位動作させる変位動作部９を備える。付勢力調整部８は、荷保持部３の前記変位動作に連動して前記付勢力を調整する。【選択図】図８
