The invention provides an end mould body of a stairway mould. The end mould body is arranged on a base of the stairway mould and comprises end mould main bodies and adjusting mechanisms, the lower ends of the adjusting mechanisms are connected with the base, the upper ends of the adjusting mechanisms are supported on the end mould main bodies, and the end mould main bodies can move and/or rotate relative to the base. The end mould body, adopting the structure, of the stairway mould is used for pouring the ends of a stairway, and when the end mould body rotates relative to the base, the included angles between the ends of the stairway and a stairway stepping assembly can be changed. When the length of the stairway stepping assembly needs to be changed, the end mould body can move on the base, therefore, the end mould body adopting the structure can be matched with different stepping assemblies and is multifunctional, and the stairways of different specifications can be produced. In general, the end mould body of the stairway mould has the advantages of being simple in structure, low in production and usage cost and high in universality. On the other hand, the invention further provides the stairway mould including the above end mould body.
