Clutched motor and device for opening and closing openable body

摘要

First and second clutches allow first and second tubular output shafts to pivot when a motor generates rotation at a second rotation speed or higher. A third clutch allows a pivot shaft to pivot when the motor rotates at a speed lower than a first rotation speed. A control plate is arranged at a first pivot position, second pivot position, or third pivot position. At the first pivot position, the first and second tubular output shafts are moved to positions in an axial direction allowing first and second rotated members to rotate. At the second pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the first rotated member to rotate. At the third pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the second rotated member to rotate.

主权项

1. A clutched motor comprising:
a first tubular output shaft that moves in an axial direction to rotate a first rotated member; a first rotating body rotated by a motor, wherein the first rotating body is coupled to the first tubular output shaft by a first clutch to be rotatable integrally with the first tubular output shaft; a second tubular output shaft that moves in the axial direction to rotate a second rotated member; a second rotating body rotated by the motor, wherein the second rotating body is coupled to the second tubular output shaft by a second clutch to be rotatable integrally with the second tubular output shaft; a control plate that pivots together with a pivot shaft to control movement of the first and second tubular output shafts in the axial direction; and a third rotating body rotated by the motor, wherein the third rotating body is coupled to the pivot shaft by a third clutch to be rotatable integrally with the pivot shaft, wherein: each of the first, second, and third clutches is a centrifugal clutch; the first and second clutches are configured to allow the first and second tubular output shafts to pivot when the motor generates rotation at a second rotation speed or higher and to stop pivoting of the first and second tubular output shafts when the motor generates rotation at a speed lower than the second rotation speed; the third clutch is configured to allow the pivot shaft to pivot when the motor generates rotation at a speed lower than a first rotation speed, which is lower than the second rotation speed, and to stop pivoting of the pivot shaft when the motor generates rotation at the first rotation speed or higher; the control plate is controlled to be arranged at a first pivot position, a second pivot position, or a third pivot position; at the first pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing the first and second rotated members to rotate; at the second pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the first rotated member to rotate; and at the third pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the second rotated member to rotate.
