Claims

[Scope of utility model registration request]

For precision press parts that have uneven parts with a depth greater than % of the thickness of the plate, it is possible to prevent the uneven parts from digging into the parts without impairing alignment when several parts are lined up, and to increase the spacing between the parts. The concave shape of precision press parts is characterized by having a step approximately half the depth of the concave part to improve the cleaning effect of the parts.
