PROBLEM TO BE SOLVED: To provide a stamp which can make a compression level of an ink reservoir uniform during stamping, even in case the stamp has a rocking structure in its assembly. SOLUTION: In this stamp, a cylindrical rib 116 and a bowed rib 117 are formed with a guide member 123 sandwiched in between, on the opposite side to a support case 201 of a retaining member 120. In addition, the rib 116 and the rib 117 do not come into contact with the support case 201 in the state that a fixed printing part 100 is apart from a main body case 2. Since helical grooves 121 in the retaining member 120 and bosses 2c on the inside part of the main body case 2 are engaged with each other, the fixed printing part 100 can rock in a direction crossing an exposed hole 114, centering around an axis linking a pair of engagement parts each between the boss 2c and the helical groove 121 as a rocking pivot. Further, the rib 116 and the rib 117 come into contact with the end part of the support case 201 by fitting the fixed printing part 100 inside the main body case 2. Consequently, the rocking motion is regulated by the rib 116 and the rib 117 and the fixed printing part 100 is no longer shaky. COPYRIGHT: (C)2006,JPO&NCIPI
