Abstract: There is provided a vehicle seat (car seat) comprising a seat cushion pad (seat body) having an air passage connected to an outlet port (114), and a blower having an inlet port (113) and configured to feed air taken in through the inlet port (113) to the air passage. The blower (100) is located on the lower side of the seat cushion pad (seat body) that is opposite to an occupant's side on which an occupant is to be seated, and the inlet port (113) is directed upward that is a direction toward the seat cushion pad (seat body).

Abstract: A strain wave gearing with a built-in motor is provided with a motor, a wave gear mechanism enclosing the motor coaxially, and a heat-insulation spacing formed therebetween. The wave gear mechanism has a wave generator attached to the motor rotor so as to rotate integrally with the motor rotor. A wave generator plug of the wave generator is fixed to a rotor magnet back yoke of the motor rotor so as to enclose the rotor magnet back yoke. The spacing is formed in a contact surface portion between the rotor magnet back yoke and the wave generator back yoke, whereby heat transfer from the motor to the wave gear mechanism is suppressed.
