PURPOSE:To prevent die-stamped images from becoming unclear near both ends, by making uniform the pressing-in quantity and the pressing-in force of die- stamping parts against a surface to be die-stamped at each part. CONSTITUTION:Die-containing holes 7, 7 opened to the tip side of a main body 3 are provided in parallel with each other at the tip part of the main body 3, and dies 4, 4 are individually slidably contained in the holes 7, 7. A sealed chamber 9 containing an oil 8 as a fluid is provided at an intermediate part of the main body 3. Through-holes penetrating from bottom parts of the holes 7, 7 to the chamber 9 are provided, and sliding pins 5, 5 are inserted through the through- holes with the outer peripheries thereof maintained to be airtight. In this case, when a die-stamping force is externally exerted on the main body 3 in the condition wherein the die-stamping parts 11, 11 are brought into contact with the surface 2 to be die-stamped, the die-stamping force is imparted to the dies 4 through the oil 8 and the pins 5. |
