  "textContent": "A door opening/closing device includes a motor and an output shaft arranged on a line extending from the axial center of the motor, power of the motor being transmitted to the output shaft via a deceleration mechanism. The door opening/closing device opens and closes a door via the output shaft by driving the motor. The positional deviation on both end surfaces of the output shaft is set to equal to or higher than Æ0.01 and equal to or lower than Æ0.1. The deceleration mechanism has a planetary gear mechanism including a sun gear arranged on a line extending from the axial center of the output shaft. The positional deviation or the coaxiality of the axial center on at least one of end surfaces of the sun gear with respect to the axial center on a datum plane orthogonal to the axial center of the sun gear is set to equal to or higher than Æ0.01 and equal to or lower than Æ0.1. Thus, the door opening/closing device has high output efficiency.",
