The present invention relates to an integrated needle roller bearing to be installed on a bearing joined to each of multiple gearshifts of a manual transmission or on each side of a planetary gear of an automatic transmission. The integrated needle roller bearing comprises a radial bearing part which is shaped into a cylinder and on which multiple radial rollers are arranged along the cylindrical shape; and an axial bearing part which has a radial shape, of which the inner tip end is joined to one end of the radial bearing part, and on which multiple axial rollers are arranged along the radial shape. Thus, the present invention improves the durability of the integrated needle roller bearing by increasing space utilization around the bearing and increasing a space for allowing lubricating oil to flow. |
