To provide a meal serving wagon that restrains rocking back and forth like a balance with a fixed wheel arranged between a front side free wheel and a rear side free wheel as a fulcrum.SOLUTION: A meal serving wagon 10 comprises a storage chamber 12, and the meal serving wagon 10 also comprises a chassis 32 loaded with the storage chamber 12, a front side free wheel 36 arranged on a front side of the chassis 32 and whose direction can be changed, a rear side free wheel 38 arranged on a rear side of the chassis 32 and whose direction can be changed, and a fixed wheel 40 arranged on the chassis 32 between the front side free wheel 36 and the rear side free wheel 38 and whose direction is fixed. When the meal serving wagon 10 is placed on a flat surface F, the front side free wheel 36, the rear side free wheel 38, and the fixed wheel 40 are in contact with the flat surface F respectively, and the contact pressure of the front side free wheel 36 and the rear side free wheel 38 against the flat surface F is lower than the contact pressure of the fixed wheel 40.SELECTED DRAWING: Figure 6
【課題】前側自在輪及び後側自在輪との間に配された固定輪を支点として、前後に天秤状に揺れ動くことを抑える配膳車を提供する。【解決手段】配膳車10は貯蔵室12を有する配膳車10であって、貯蔵室12を積載する車台32と、車台32の前側に配され、車輪の向きを変更可能な前側自在輪36と、車台32の後側に配され、車輪の向きを変更可能な後側自在輪38と、車台32の前側自在輪36と後側自在輪38との間に配され、車輪の向きが固定された固定輪40と、を備え、当該配膳車10が平らな平面F上に置かれている状態において、前側自在輪36、後側自在輪38、及び固定輪40はそれぞれ平面F上に接地するものとされ、前側自在輪36、及び後側自在輪38の平面Fに対する接地圧は、固定輪40の接地圧よりも低くなっている。【選択図】図6
