PROBLEM TO BE SOLVED: To reduce contact surface pressures in the areas by increasing contact areas between large diameter side rings of respective pockets of a holder and large diameter side end surface of respective conical rollers. SOLUTION: In the conical roller bearing 10, the large diameter side ring 24 of respective pockets 22 of the holder 20 is provided with a recessed cylindrical surface 24a, whose curvature R is larger than the curvature Ra of the large diameter side end surface 11a of respective conical rollers 11.
