The seal member opening means (7) in this cylinder device is formed by firmly fitting a seal member opening pointed member (10) in a guide member (9), which is provided slidably in the holding means (8) formed in the front end portion of the cylinder (1), in such a manner that the pointed member (10) projects from the front end surface of the guide member (9). A gas discharge hole is made in the seal member (3) by slidingly moving the seal member opening means (7). |
