PROBLEM TO BE SOLVED: To provide a stamp of which stamp surface can be changed over between a stamping-possible state and a stamping-impossible state with simple knocking operation, and in which simple turn of an upper outer cylinder holder relative to a lower outer cylinder holder disables the knocking operation.SOLUTION: A stamp, in which a printing body 10 existing at a lower end of an outer cylinder holder having an upper outer cylinder holder 1 and a lower outer cylinder holder 2 linked to each other in a relatively turnable manner can be projected/retracted from the lower end of the outer cylinder holder by knocking operation so as to be changed over between a stamping-possible state and a stamping-impossible state, includes a printing body holder 9 having a printing body cylinder receiving part 9a continuing the lower part of a shaft 9b thereof and slidably fitted into the lower outer cylinder holder 2, the shaft 9b being loosely fitted into the upper outer cylinder holder 1 in key-engagement with a cylindrical connector 3, wherein a knock cap 5 is provided at the upper end of the shaft 9b via a knock mechanism 11, and a lock member 6 is provided on the upper outer cylinder holder 1 for engaging/disengaging with/from a key 9c formed on the shaft 9b by the knocking operation of the knock cap 5. |
