ABSTRACT:
A durable door opening/closing mechanism that does not require a large space for opening and closing operation such that a door and a main body such as a cab, can be freely designed. To achieve this, the door is supported by links coupled to the cab by joints. One end of the door is guided along the side of the cab by a guide rail. When a rail support begins moving along the side of the cab while being guided by the guide rail, a couple of forces, causing the door to rotate, act on the joints at both ends of the links. The other end of the door is swung out of the cab towards the outside by the couple of forces.
