Toilet device

A toilet device, comprising:

• an electric opening/closing unit configured to open and close at least one of a toilet seat or a toilet lid,
• the electric opening/closing unit including
• a motor, and
• a transmission mechanism transmitting a rotation of the motor to one of the toilet seat or the toilet lid,
• the transmission mechanism including
• an internal gear including teeth provided in an inner circumferential surface of the internal gear, the internal gear being tubular,
• a first transmission part housed in the internal gear, the first transmission part transmitting a rotational force of the motor, and
• a second transmission part housed in the internal gear, the second transmission part transmitting a rotational force of the first transmission part,
• the first transmission part including
• a first planetary gear to which the rotational force of the motor is transmitted, the first planetary gear revolving around a rotation axis along the inner circumferential surface of the internal gear while rotating, and
• a first planetary carrier rotating around the rotation axis as the first planetary gear rotates and revolves,
• the second transmission part including
• a second planetary gear to which a rotational force of the first planetary carrier is transmitted, the second planetary gear revolving around the rotation axis along the inner circumferential surface of the internal gear while rotating,
• a second planetary carrier rotating around the rotation axis as the second planetary gear rotates and revolves, and
• a shaft part including a rotational axis of the second planetary gear, the shaft part revolving around the rotation axis,
• the first planetary carrier including a protrusion extending along a trajectory of the revolution of the shaft part,
• the shaft part contacting the protrusion,
• a gap being formed between the shaft part and a part of the first planetary carrier other than the protrusion.
