Abstract
To provide a roller for a crawler type traveling vehicle. The manufacture of this roller is streamlined by simplifying a structure for holding a seal mechanism between a bearing part and the outside and a thrust bearing and facilitating working while eliminating the need for welding. Roller pieces shaped to be axially separable are combined with a support shaft and formed integrally at a parting section (including a stepped engagement part and an external engagement part) by press fitting. The support shaft is provided with a projection for restraining the left and right roller pieces from moving in an axial direction.
