PROBLEM TO BE SOLVED: To provide a support with a costless reflecting body which is low in the forming cost, since a recess for a reflecting body can be formed at an optional position without restriction of manufacturing conditions, in supports for an inexpensive all-purpose and popular car stop or protection fence made of inexpensive metallic tubular bodies having an inexpensive raw material such as stainless or steel pipes.
SOLUTION: A press die 3 in which a recess 11 for attaching a reflecting body is formed by press working inexpensive in the pressing work cost is constituted of a die 30 supporting the hollow internal wall face of the support and a punch 33 pressing the side face of the support body 10 correspondingly with the die 30. The die 30 is diametrally enlarged or contracted when it is required during pressing work to make it possible to support or release the hollow internal wall face. The side face of the support body 10 is pressed by the punch 33 corresponding thereto to form a recess.
