A paper sheet conveying roller is constructed with a roller body (20) attached to an outer peripheral side of a support body (12). The roller body (20) is provided with a tubular section (21), which is arranged to form a cavity (19) between the support body (12) and the tubular section (21), and ring-shaped side walls (22, 22) that are interconnected, respectively, with both ends of the tubular section (21) in the axial direction thereof. Two annular grooves (13, 13) and first and second branched grooves (14A, 14B) branched out from the respective annular grooves (13, 13) are formed on the outer peripheral surface of the support body (12). Inner peripheral edges (25, 25) of the side walls (22, 22) are fitted in the annular grooves (13, 13). The inner peripheral edges (25, 25) are provided with first and second protrusions (26A, 26B) that protrude bilaterally in the axial direction. The protrusions (26A, 26B) are fitted in the branched grooves (14A, 14B). |
