A hand-held pneumatic device, such as a C ring clamping device, comprises a main body (10), a grip (18) joined to a lower portion of the main body (10), a pneumatic cylinder (16) contained in the main body (10), and a directional control valve (20) contained in the main body (10). A first air discharge passage (30) formed in the grip (18) is connected to a first discharge port (20a) of the directional control valve (20) and has an open end in a lower end portion of the grip (18). A second air discharge passage (32) formed in the main body (10) is connected to a second discharge port (20b) of the directional control valve (20) and has an open end opening in a back portion of the main body (10). The open end (32a) of the second air discharge passage (32) is connected to an inner portion (30a) of the first air discharge passage (30), near the first discharge port (20a) of the directional control valve (20), so that air is discharged through the open end of the first air discharge passage (30). <IMAGE> |
