Patent ID: 7819203

Claim:
A striking tool comprising: a cylinder casing; a piston being disposed within the cylinder casing; a striker being disposed within the cylinder casing, the striker being reciprocally movable by a change of an air pressure within an air chamber, the change of the air pressure being generated by a movement of the piston; a tip end tool to which an impact force is transmitted by reciprocal movement of the piston; an intermediate member intermediating the impact from the striker to the tip end tool; a shank sleeve surrounding the intermediate member and placed between the cylinder casing and the intermediate member; a first damper being disposed adjacent the striker to absorb a forward impact force of the striker through the shank sleeve; a second damper being disposed adjacent the tip end tool to absorb a backward impact force of the tip end tool through the shank sleeve; a tip end tool holding member holding the tip end tool and having an attachment portion attached to the cylinder casing; a first buffer member, a second buffer member, wherein the attachment portion of the tip end tool holding member is sandwiched between said first buffer member and said second buffer member in an axial direction of the striker; a collar inserted through a hole portion of the attachment portion of the tip end tool holding member the first buffer member, and the second buffer member; and a bolt inserted through the collar to engage the tip end tool holding member with the cylinder casing, wherein an inner diameter of the hole portion of the attachment portion of the tip end tool holding member is larger than an outer diameter of the collar such that an empty space is disposed between the attachment portion and the collar.
