To provide a method by which propagation of vibrations and noises into a vehicle body inside is effectively suppressed by means of a simple constitution without increases of weight and cost.SOLUTION: A track type vehicle 1A comprises a vehicle body, a suspension frame 30, a truck frame, a traction link 40, a drive part and a sliding contact member 50A. The suspension frame 30 is fixed to a lower part of the vehicle body. The suspension frame 30 extends down the vehicle body. The truck frame supports wheels in rotatable fashion. The traction link 40 extends in a vehicle traveling direction and has a first end connected to the truck frame. The traction link 40 has a second end 43b connected to the suspension frame 30. The drive part drives the wheels to rotate. The sliding contact member 50A is arranged between the second end 43b of the traction link 40 and the suspension frame 30. The sliding contact member 50A slides on and contacts with the second end 43b elastically.SELECTED DRAWING: Figure 4

    【課題】重量増加、コスト増加を抑えつつ、簡易な構成で、振動や騒音の車体内への伝播を有効に抑える。【解決手段】軌道式車両1Aは、車体と、懸架枠30と、台車枠と、牽引リンク40と、駆動部と、摺接部材50Aと、を備える。懸架枠30は、車体の下部に固定されている。懸架枠30は、車体の下方に向かって延びる。台車枠は、車輪を回転可能に支持する。牽引リンク40は、車両進行方向に延びて第一端が台車枠に連結される。牽引リンク40は、第二端43bが懸架枠30に連結される。駆動部は、車輪を回転駆動する。摺接部材50Aは、牽引リンク40の第二端43bと懸架枠30との間に設けられる。摺接部材50Aは、第二端43bに弾性的に摺接する。【選択図】図4
