An ink occlusion body 17 is fitted in the inner hole 9, and a cover 18 is press-fitted and fixed to the outer peripheral portion of the shaft portion 8a while holding the printing body 15 and the ink occlusion body 17. In addition, the porosity of the ink occlusion body 17 and the hole gradient that decreases toward the printing body 15 are taken into consideration so that the ink contained in the ink occlusion body 17 is guided to the printing body 15, and the marking is accompanied. Ink is supplied to the printing body 15 by expansion and contraction of the printing body 15 and the ink occlusion body 17.

Further, the shaft portion 8b of the holder 8 is formed with a projecting engagement portion 12 on the outer periphery of the rear end portion via a step portion 11. On the other hand, the front shaft 2 has a large diameter inner hole 3 in the front shaft portion 2a, and a hole portion having a step portion 5 in the rear through a step portion 4 penetrates to the rear end. A groove-shaped engaging portion 6 is formed on the inner surface of the inner hole near the rear end. In addition, a groove-shaped engaging portion 7 that engages with an engaging portion 26 of a grip 25, which will be described later, is formed on the outer periphery of the shaft portion 2b. Furthermore, a groove 7a is provided which forms a ventilation path with the inner circumference of the grip 25.

As described above, the holder 8 is fitted with the cylindrical hood 13 having the collar portion 14 from the rear end side in a state in which the cover 18 is covered and the stamp surface 16 is appropriately buried, and the collar portion 14 is attached to the front shaft. The rear end of the collar 10 is in contact with the rear end of the front shaft 2, and the return spring 19 is fitted from the rear end of the front shaft 2, and the front end of the return spring 19 is in contact with the rear end of the flange 14. The rudder 8 is inserted through the inner hole 3 of the front shaft 2, the step portion 11 of the holder comes into contact with the step portion 4 of the front shaft, and the engagement portion 12 of the holder elastically deforms relative to the step portion 5 of the front shaft. Be locked by. In this state, the holder 8 is fixed to the front shaft 2, and when the front surface of the hood 13 is pressed, the hood 13 retracts against the urging force of the return spring 19 and the marking surface 16 becomes the same surface as the front surface of the hood 13 for imprinting. Becomes

Further, the handle 20 is provided with a vent hole 22 penetrating the rear end of the center hole, a sponge-like cushion material 24 is fitted behind the center hole, and ink can be occluded in the front thereof. As described above, the porous and slightly hard ink storage rod 23 having innumerable continuous pores is fitted. A protrusion or groove 28 is formed on a peripheral wall of the central hole of the handle 20 at a required position to hold the ink storage rod 23 together with the ventilation of the fitting portion. In addition, a cushion material 24 is adhered or welded to the rear end of the ink occlusion rod 23 to integrate them, and the ink occlusion rod 23 is loosely fitted into the central hole of the handle 20 so that the cushion material 24 is formed in the central hole. On the other hand, it is possible to expand and contract, but it is also possible to make an appropriate frictional engagement so that the ink storage rod does not fall off the handle. Further, on the outer periphery of the front portion of the handle 20, there is formed a protruding engaging portion 21 that is detachably engaged with the engaging portion 6 of the front shaft 2.
