problem can be prevented and a sliding frictional resistance can be reduced as a result an ironing operation can be performed while turning the iron i thus preventing damage to the clothing c sleeves of clothings trousers skirt and the like can be ironed on the rounded iron working surface in the above description the base material 2 has a rounded surface as a part of circle with the radius r3 but may have a more complicated rounded surface referring to fig4 a and 4b the iron working surface of the pressing board 1 is rounded upward so that a contact state between an iron and the iron working surface is not a surface contact state but is approximate to the above mentioned line or point contact state the pressing board 1 is constructed as follows a cushion material 4 with proper shock absorbing property and uniform thickness is arranged under a covering cloth 3 covering the entire iron working surface of the pressing board 1 ends of the cloth 3 are fixed to the base material 2 by a plurality of rivets not shown or laces 14 foldable legs 6 on the distal ends of which rubber shoes 7 are fitted under pressure are provided to the back.
