PROBLEM TO BE SOLVED: To provide a display apparatus which attracts people attention by moving a usually stationary signboard and which is not complicated and inexpensive and in which a display content is variable. SOLUTION: A crank is attached to a rotation shaft of a motor and a rod which is connected to the crank via the shaft and a rod shaft are connected and the rod shaft is connected to a linking base with a moving bearing. Consequently, by rotating the crank, the linking base is moved reciprocately by two guide shafts which penetrate a bush bearing which touches linking base. A signboard adapter plate connected to the linking base via a supporting post also interlocks and moves reciprocately. Moreover, by providing a hook in which a pulling spring is connected to the adapter plate and by hooking and fixing the tension spring to a corner part of the display plate, deviation of the display plate due to wind pressure and vibration is prevented when using and as the display content is easily exchanged by a structure without danger of sliding down and with easy mounting and demounting, an application field is expanded.
