Abstract:
Provided are a magnetic gear device (10) and a rotating electrical machine (100) having intermediate cylindrical portions with increased rigidity against radial-direction external forces. In a magnetic gear device (10) and a rotating electrical machine (100) according to the present invention, an intermediate cylindrical portion (1) includes: magnetic-pole portions (4) arranged in a circumferential direction; frame-shaped spacers (5) penetrating in the radial direction, arranged in the circumferential direction alternately with the magnetic-pole portions (4), and each having two side-wall portions (5a, 5b) contacting with the adjacent magnetic-pole portions; end plates (20) provided at both ends of the magnetic-pole portions (4) and the spacers (5) in an axial direction of a rotary shaft (101); and reinforcement portions (14) placed inside the spacers (5) while being pressed to inner surfaces of the side-wall portions (5a, 5b) in the circumferential direction, to apply forces in the circumferential direction to the adjacent magnetic-pole portions (4) via the spacer (5).
