Drive device

A drive device, comprising:

• a motor portion that has
• a rotor having a first shaft rotatable about a rotation axis extending in an axial direction, and
• a stator disposed radially outward of the rotor;
• a gear portion that is attached to one axial direction side of the first shaft;
• a housing that accommodates the motor portion and the gear portion;
• and
• a fluid flow path configured to allow a fluid to flow through,
• wherein
• the gear portion has a second shaft connected to one end portion of the first shaft in the axial direction,
• the housing includes
• a housing tubular portion that extends in the axial direction and accommodates the motor portion,
• a partition wall that closes one end portion of the housing tubular portion in the axial direction, and
• a gear side lid portion that is disposed at one end portion of the partition wall in the axial direction and constitutes a gear accommodation portion that accommodates the gear portion in cooperation with the partition wall,
• the fluid flow path has a first flow path, a third flow path, a fourth flow path, and a sixth flow path,
• one end portion of the first flow path is connected to the gear accommodation portion,
• the third flow path is disposed inside the partition wall and extends in a direction intersecting with the rotation axis,
• one end portion of the third flow path is connected to the gear accommodation portion through the first flow path,
• the fourth flow path is connected to an other end portion of the third flow path and extends toward the gear side lid portion,
• one end portion of the sixth flow path is connected to the other end portion of the third flow path, and
• an other end portion of the sixth flow path is disposed within the housing tubular portion.
