A rotating body and a lawnmower having the same are provided, wherein the parts and the main body of the rotating body are firmly joined together. To solve this problem, the rotating body (1) includes a part (2) and a resin main body (3) integrally formed with the part (2). The part (2) includes a through hole (20) and an annular portion (22) surrounding the through hole (20). The annular portion (22) has a first surface (221) and a second surface (222) facing opposite sides in the axial direction (D1). On the first surface (221), a plurality of protrusions (26) spaced apart in the circumferential direction (D2) of the annular portion (22) are formed. The plurality of protrusions (26) are each embedded in the main body (3). none
