Abstract
The present invention relates to an end cap assembly for a nailer whose bush ring is disposed between the end cap and the moveable member, at the inner periphery and the outer periphery of the bush ring is formed an annular protrusion, respectively. At the bottom of the bush ring are provided a bush block and a plurality of backing ribs, around the periphery of the bush block are formed a plurality of spiracles. The bush ring has multiple functions and is able to take the place of the inner seal ring, the outer seal ring, the buffering cushion and the like components of the conventional nailer. Thus, the structure of the end cap is simplified. The bush ring is formed by integral plastic ejection, thereby, the production cost and the concurrent assembly time are saved.
