<p>PURPOSE:To make an actuator compact by driving a rack plate provided with cables releasing the lock of an opening/closing body at both ends with a low- rotation, high-torque motor via one-stage reduction gears. CONSTITUTION:One-stage reduction gears 7 are provided in a casing 4 rotatably positively or reversely by a low-rotation, high-torque motor 5. A rack plate 12 is engaged with the reduction gears 7 movably to the right or the left, and hook projections 16a, 16b at the end sections of cables 15a, 15b are slidably fitted in an oblong hook groove 14. Stoppers 18a, 18b provided in the casing 4 are coupled in grooves 22a, 22b formed on the plate 12 via a partition section 23 to adjust the stroke. Coil springs 24a, 24b are provided in the grooves 22a, 22b to return the plate 12 to the intermediate position when the motor 5 is not operated. The motor 5 is rotated, the desired side of the cables 15a, 15b is pulled, and the lock at the tip section of the cable is released. Since the one-stage reduction gears 7 are used, the whole actuator can be made compact.</p> |
