<p>PROBLEM TO BE SOLVED: To provide a linear shuttle system capable of extending a pair of front and rear branch rollers simultaneously at all times from a vehicle. SOLUTION: A linear shuttle system is provided with a pair of front and rear oscillating arms 11 and 12 which extend or retract a pair of front and rear branch rollers 13 and 134 by oscillation, a rotating member 20 arranged between the pair of front and rear oscillating arms 11 and 12, a motor 19 which rotates the rotating member 20, and a pair of links 21 and 22 which connect the rotating member 20 to the pair of oscillating arms 11 and 12. When the rotating member 20 is rotated by the motor 19, the oscillating arms 11 and 12 are oscillated simultaneously through the links 19 and 22 so as to extend or retract the pair of front and rear branch rollers 13 and 14 simultaneously to the side part of a vehicle.</p> |
