特徴とする打込機の可変排気カバー装置。 In a driving machine that uses compressed air as a power source and is equipped with an exhaust port for discharging the compressed air consumed during the driving process to the outside air, at least one protrusion A or recess A is formed near the exhaust port, Furthermore, the exhaust port is provided with an exhaust cover made of a flexible material such as rubber and whose exhaust direction is variable, and the exhaust cover is provided with a concave portion B or a convex portion B that engages with the convex portion A or concave portion A. , when the exhaust cover is rotated to change the exhaust direction, the concave part B or convex part B of the exhaust cover becomes convex part A or concave part A due to elastic deformation of the rubber.
rides on it, becomes rotatable, and then moves onto the convex part A again.
Alternatively, a variable exhaust cover device for a driving machine, which is capable of engaging with the recess A.
