Rail vehicle having guide device

A rail vehicle having a guide device, the guide device being configured to guide traveling of a bogie on a traveling track by rolling guide wheels in a state of bringing the guide wheels into contact with guide rails installed on both sides of the traveling track in a vehicle width direction perpendicular to a traveling direction, wherein:

• the guide device has an arm and the guide wheels, the arm having a central portion fixed to a stationary member, extending to both sides in the vehicle width direction, and having both end portions elastically deformable in a front-and-rear direction in which the guide rails extend, the guide wheels being mounted on the arm at the both end portions of the arm;
• a position of a rotation center of each of the guide wheels in the front-and-rear direction is displaced from a center line of the arm, the center line extending in the vehicle width direction;
• and
• a transverse section of the arm is an I-shape in which a width of each of flange portions of horizontal upper and lower ends of the I-shape is smaller than a dimension of a central portion extending in a vertical direction between the flange portions.
