Abstract:
A linear extension and retraction mechanism includes: a plurality of first pieces connected bendably with each other; a plurality of second pieces connected bendably with each other; and a plurality of rollers configured to cause the first pieces to join the second pieces so as to form an arm section in the form of a columnar body, and configured to support the arm section in a longitudinally movable manner. A drive gear is arranged behind the plurality of rollers, and the drive gear is configured to send out the first and second pieces forward from the plurality of rollers, and to pull back the first and second pieces to the plurality of rollers. The drive gear is engaged with linear gears on back surfaces of the plurality of first pieces. The drive gear is coupled to a motor unit by way of a power transmitting mechanism. The power transmitting mechanism includes a pair of bevel gears, and one of the pair of bevel gears is coupled to an output shaft of the motor unit, and the other of the pair of bevel gears is coupled to a rotary shaft 45 of the drive gear.
