PROBLEM TO BE SOLVED: To provide an elevation type scaffold block of a substantially constant ladder width easy to be moved, and capable of enhancing a withstanding load of an elevation part by a ladder body. SOLUTION: A pair of bearing parts 12 is projected upwards on the respective both sides of opposed sides 8 of each elevation frame 2 of the elevation part 4, lower ends of both side vertical frames 10 of the ladder body 9 are provided between projected tips of the pair of bearing parts 12, the space between base ends of the paired bearing parts 12 is made to serve as a hooking clearance 13, a hooking part 11 is provided at the upper end of both the side vertical frames 10 of the ladder body 9, the hooking part 11 is formed into a hook shape inserted through the hooking clearance 13, to be hooked to the opposed sides 8 of each elevation frame 2, and the upper and lower both-side vertical frames 10 of the ladder body 9 are juxtaposed vertical-directionally on a substantially straight line, when the hooking part 11 is inserted through the hooking clearance 13, to be hooked to the opposed sides 8, in the elevation type scaffold block.
