A movable body is a tricyclic movable body automatically moving and includes: a first steering wheel steerable but not drivable; a second steering wheel steerable but not drivable and provided on a side in a first direction with respect to the first steering wheel; and a drive wheel steerable and drivable and provided on a side in a second direction orthogonal to the first direction with respect to the first steering wheel and the second steering wheel.

Movable body, method for controlling movable body, and non-transitory computer readable storage medium storing program

A drive device for an electric vehicle includes: a motor configured to be in a drive wheel of the electric wheel; and a reduction gear configured to reduce rotational speed of the motor and transmit resultant rotation to the drive wheel; the reduction gear including a sun gear configured to be driven by the motor, a first planetary gear that is configured to mesh with the sun gear and has a first number of teeth, a fixed ring gear that is meshed with the first planetary gear and arranged non-rotatably, a second planetary gear that is coupled to the first planetary gear and has a second number of teeth that is smaller than the first number of teeth, a movable ring gear that is meshed with the second planetary gear and arranged rotatably, and a transmission member configured to transmit rotation of the movable ring gear to the drive wheel.

Drive device for electric vehicle and electric vehicle

A power transmission device includes a first power transmission path for transmitting a driving force of a motor to one driven shaft, and a second power transmission path for transmitting the driving force of the motor to another driven shaft. At least one of the first power transmission path or the second power transmission path includes a first intermediate rotor fixed to an output shaft of the motor, a second intermediate rotor rotated by the first intermediate rotor and moving arcuately along an outer circumference of the first intermediate rotor, a driving shaft rotated by the second intermediate rotor and transmitting the driving force to the one driven shaft or the another driven shaft. The driving shaft is configured to move in a direction perpendicular to an axial center direction of the driving shaft in accordance with movement of the second intermediate rotor around the first intermediate rotor.
