The invention provides a rear sprocket for a human-powered vehicle, which can improve strength and rigidity and can realize light weight. A rear sprocket (47) is used for a bicycle (1). The rear sprocket (47) is provided with an outer ring-shaped body (57), a plurality of sprocket teeth (59), an inner ring-shaped body (61), and a connecting arm (63). The connecting arm (63) has a radially outer half section (65) and a radially inner half section (67). The second circumferential width (W2) of the radially inner half section (67) is smaller than the first circumferential width (W1) of the radially outer half section (65). The connecting arm (63) is formed in a tapered shape from a first radial position (RP1) toward a second radial position (RP2).

    本发明提供一种能够提高强度及刚性且能够实现轻量化的人力驱动车辆用后链轮。后链轮(47)用于自行车(1)。后链轮(47)具备外侧环状体(57)、多个链轮齿(59)、内侧环状体(61)、以及连结臂(63)。连结臂(63)具有径向外侧半段(65)和径向内侧半段(67)。径向内侧半段(67)的第二周向宽度(W2)比径向外侧半段(65)的第一周向宽度(W1)小。连结臂(63)从第一径向位置(RP1)朝向第二径向位置(RP2)而形成为锥状。
