Abstract
In a safety device for a nailing machine which has a compressed air introducing opening for introducing a compressed air therefrom and an air chamber for storing compressed air introduced from the compressed air introducing opening, the safety device comprises a compressed are passage, a relief valve and a spring. The compressed air passage is provided close to an inner side of the introducing opening, and communicates with the air chamber. The relief valve serves to release the compressed air within the air chamber outside, and has a valve housing, an air leak hole and a valve stem. One end of said valve housing is open onto the air chamber, the other end of the valve housing is open onto the introducing opening, a middle portion of the valve housing communicates with the air leak hole which communicates with the outside. The valve stem is slidably accommodated in the valve housing, one end of the valve stem faces the air chamber and the other end thereof faces the introducing opening. And a spring urges the valve stem toward the air chamber, so that when the valve stem slides toward the introducing opening, the air chamber is caused to communicate with the air leak hole.
