[Effect]

According to this pressurizing device, the flat end surface of the pressurizing part is brought into contact with the flat surface of the pressurized member, Axial pressure from the drive member is applied through the convex member, thrust bearing, and pressure member. Transmitted to the pressure member. Since the convex member and the thrust bearing make point contact, the axes of the pressurized member and the pressurizing member are Even if it is tilted, because the point contact part is tilted, it will not move in the axial direction of the pressurized member. The flat end surface of the pressure member can be brought into close contact with the vertical flat surface. Therefore, the driving member axial compressive force is applied in the axial direction of the pressurized member through the convex member, thrust bearing, and pressure member. Can communicate accurately.

A large-diameter disk portion 3 is formed on the other end side of the pressure member 1; A concave surface 1a is formed in the center of the hole. The base of the disc portion 3 has a conical inclined surface 4. It is formed. A disk-shaped holding member 14 is housed in the concave surface 1a, and a thrust bearing is mounted on the end surface 14a. ball 8 comes into contact with it. The ball 8 is housed in a guide member 9 shown in FIG. child The protrusion 7 of the disc 6 is inserted into the central hole 9a of the thrust bearing 22. This convex part 7 guides the thrust bearing 22. Compression coils are arranged at 120° intervals around the outer circumference of the disk 6. One end 12a of the spring 12 is pressed, and the other end 12b abuts against the inner wall 3a of the disc portion. ing. Similarly, compression coil springs are arranged at 120° intervals on the outer circumference of the guide member 9. One end 13a of 13 is in contact, and the other end 13b is in contact with the disk inner wall 3a.

[0007] The storage member 16 is cylindrical and has an annular inclined surface 17 at its end. this The disk portion 3 of the pressure member 1 is inside the storage member 16 passing through the hole formed by the inclined surface 17. The disk portion 3 is housed in such a way that it does not fall out from the hole 17a. The inclined surface 17 and the inclined surface 4 are formed to have the same inclination angle, and are at an angle that allows surface contact with each other. is set to . A load cell 10 is provided inside the storage member 16. load cell 10 A hemispherical portion 11 is fixed to the top. The drive shaft is located on the opposite side of the storage member 16 from the hole 17a. 18 is fixed, and this drive shaft 18 is connected to a cylindrical guide member 20 via a bearing 21. It is stored so that it can be slid freely.

[0008] The pressing force transmitted from the drive source to the drive shaft 18 downward in FIG. , convex portion 11, disk top surface 6a of thrust bearing 22, ball 8, holding member 14, pressure The pressure is transmitted through the member 1 to a pressurized member (not shown) that contacts the end surface 2a. The state shown in FIG. 1 shows a state in which the pressurized member is not in contact with the flat surface 2a. Figure 3 As shown in FIG. The inclined surface 4 of the pressure member 1 lifts, and the top surface 6a contacts the hemispherical portion 11.
