PROBLEM TO BE SOLVED: To provide the frame structure of a movable display board, in which leg bodies are locked stably to a fixed frame at the time of housing and using, and which can be used by inverting upper and lower sections. SOLUTION: Notched sections 41, 42 in the vertical direction centering around a shaft 6 and notched sections 43, 44 in the oblique direction are formed to upper and lower sections respectively in a supporting metal fitting 4, in which a leg body 3 can be rotated at 180 deg. by the shaft 6, while stopper sections 53 capable of being engaged and disengaged with and from the notched sections 41, 42 in the vertical direction and the notched sections 43, 44 in the oblique direction by the elastic force of a spring 7 are formed at the front ends of the left-right vertical levers 51 of a locking lever 5 interlocked with the leg body 3 and turned. The leg body 3 is adjoined in approximately parallel with a fixed frame 2 while the stopper sections 53 of the locking lever 5 are locked to the notched sections 41, 42 in either vertical direction of upper and lower sections at the time of the nonuse, and the leg body 3 is opened slantingly while the stopper sections 53 of the locking lever 5 are engaged with the notched sections 43, 44 in either oblique direction of upper and lower sections at the time of usage. |
