摘要： A tool holder (100) for holding a tool (200) has pressurizing chambers (123a, 123b) provided between a body member inner peripheral surface (111) of a body member (110) and a sleeve outer peripheral surface (122) of a sleeve (120). Grip parts (124a, 124b) are provided between the sleeve outer peripheral surface and a sleeve inner peripheral surface (121) and are elastically deformed radially inward when pressure in the pressurizing chambers is increased. An extended chamber (123d) is defined between the sleeve outer peripheral surface and the body member inner peripheral surface, fluidly communicates with the pressurizing chamber and extends in an axial direction and in a circumferential direction. The extended chamber curtails radially inward elastic deformation of a portion of the body member inner peripheral surface, which corresponds to one of the grip parts, when a pressing force is received on a body member outer peripheral surface (112).

摘要： A chucking device of the present invention includes an annular elastic member sandwiched between an upper and a lower member. A rod is slidable up and down in a bore formed in the upper and lower members and is partly positioned in the elastic member. The rod presses the elastic member radially outward when raised or lowered, thereby causing the chucking device to chuck a hollow, cylindrical base. The elastic member contacts the inner periphery of the base over a minimum of area and surely, closely contacts it for thereby implementing desirable sealing. The chucking device can therefore form a uniform film on the outer periphery of the base.

摘要： Provided is a holder device that uses a pressure medium suitable for gripping a long and thin grasped object, the device eliminating need for a small-diameter machining for a device body and allowing use of a material suitable for sleeve deformation at a portion where a pressure chamber is formed. A holder device capable of deforming in a radial direction for fastening a grasped object 7 through a function of a pressure medium, includes a device body 2, a sleeve 3 disposed at a leading end of the device body 2 for gripping the grasped object 7, a pressure chamber 8 formed circumferentially in the sleeve 3, and a support portion 9 provided continuously from the device body 2 for forming the pressure chamber 8 together with the sleeve 3.

摘要： A chucking mechanism which reliably attaches and detaches a disc with high precision. The chucking mechanism includes a shaft for supporting the disc and having a tapered recess, a tapered cone adapted to fit in the tapered recess, and a piston for moving a rod, attached to the tapered cone, through a hole formed in the shaft. The mechanism also includes an O-ring having a variable diameter and being disposed between the tapered cone and the tapered recess. As the piston moves the tapered cone in a first direction, the tapered cone gradually expands the diameter of the O-ring to press and fix the disc. As the piston moves the tapered cone in a second direction, the diameter of the O-ring gradually contracts to move out of contact with the disc so as to release the disc.
