PROBLEM TO BE SOLVED: To provide a structure of a slope face protection wall having difficulty in falling forward against earth pressure from the back with a simple constitution and facilitating the execution and manufacture with a simple structure of a block body. SOLUTION: A back projection 2 is projected to the central part in the direction of the width of the back section of a main body 1 as a parallelepiped or a cube to form the block body 3. The lower end of the back projection 2 is projected downward of the lower end of the main body 1 to make it as an engaging section 5. A plurality of block bodies 3 are arranged in the lateral direction and, at the same time, vertically piled up to constitute the slope protection wall 4. The block bodies 3 adjacent to each other in the lateral direction are brought into contact with each other at the side part of the main body 1 and, at the same time, the block bodies 3 adjacent to each other in the vertical direction are brought into contact with each other at the vertical surface part in a state to move them in the lateral direction. The engaging section 5 on the lower end of the back projection 2 of the main body 1 of the block body 3 is fitted between two back projections 2 of the main bodies 1 of two block bodies 3 adjacent to each other in the lateral direction under the block body 3.
