A robot (1) includes a base (3). A turnable portion (5) is mounted on the base and turnable about a first axis (Ax1) approximately perpendicular to an installation surface on which the base (3) is disposed. An arm (7) is mounted on the turnable portion (5) and swingable about a second axis (Ax2) parallel to the installation surface. A first motor (20) is accommodated in the turnable portion (5) and moves the turnable portion about the first axis (Ax1). A first motor includes a body (30) and a protrusion (70). The body (30) has an axial dimension that is in a direction along an output shaft (Ax) of the first motor (20) and that is smaller than a perpendicular dimension in a direction approximately perpendicular to the output shaft (Ax). The protrusion (70) protrudes from a surface of the body (30) in a direction along the output shaft (Ax) and is displaced from the output shaft (Ax). A second motor (20) moves the arm (7) about the second axis (Ax2).
