A scalar arm is provided to connect a front end of a pre-arm and a connective shaft to each other by using a synchronization unit. A scalar arm includes a pair of pre-arms(4), a supporter(1), a transfer arm(5), and a synchronization unit(6). Each of the pre-arms is composed of two arms(2,3). Each of the pre-arms is attached rotatably at the supporter. The transfer arm is formed to connect rotatably front ends of the pre-arms with each other. Connective shafts are fixed to front ends of the pre-arms connected to the transfer arm. The synchronization unit connects the connective shafts to each other. The synchronization unit includes a pair of gears and a synchronous rotation motor unit for rotating the connective shafts.
