Conventionally, a ceramic fishing line guide pulley A as shown in Fig. 1 has been manufactured by first putting a ceramic raw material into a mold, press-molding it to obtain a cylindrical molded product, and firing this. There is. As a result of this firing, the molded product shrinks by approximately 20%. However, during firing, the shrinkage of the lower side of the cylindrical molded product is hindered by its own weight, and the amount of shrinkage of the upper side becomes larger than the amount of shrinkage of the lower side. As a result, the shaft hole B becomes a tapered hole, and for example, in the case of a shaft hole with a diameter of 5 mm and a length of 10 mm, the difference in radius between the maximum circle and the minimum circle becomes as much as 0.1 to 0.2 mm. If such a guide pulley A is used, the shaft attachment will be incomplete, the frictional resistance of the thread will increase, and the life of the thread will be shortened. Therefore, after firing, we conducted a 100% inspection.
Determine whether shaft hole B is greater than the specified value (for example, 0.1 mm), and if the taper is greater than the specified value, internally grind shaft hole B with a diamond grindstone and correct the taper so that it is within the specified value. are doing. However, these operations are extremely complicated and significantly reduce productivity.

First, ceramic raw materials such as silicon nitride (Si 3 N 4 ), silicon carbide (SiC), alumina (Al 2 O 3 ), etc. are placed in a mold, and then press-formed into a cylindrical shape as shown in Figure 2. A molded article 1 is obtained and fired. An annular groove 2 having a U-shaped cross section and around which a thread is wound is coaxially formed in the middle part of the outer peripheral surface of the cylindrical molded product 1. Next, the shaft hole 3 of this cylindrical molded product 1 is
An adhesive 5 such as epoxy resin is applied to the outer circumferential surface of a cylindrical bushing 4 (see FIG. 3) made of plastic such as phenolic resin, polyamide resin, or fluororesin, which has an outer diameter larger than the inner diameter of (see FIG. 3). (See Figure 4). This bush 4 contains a slot 6. Then, as shown in FIG. 5, the bush 4 coated with the adhesive 5 is inserted into the shaft hole 3 of the cylindrical molded product 1. At this time slot 6
Due to its elasticity, the bush 4 can be smoothly inserted into the shaft hole 3. Then, the adhesive 5 is solidified to integrate the bush 4 and the cylindrical molded product 1. Thus, even if the inner surface of the shaft hole 3 of the cylindrical molded product 1 is tapered or irregularly shaped due to shrinkage due to firing, the bush 4 makes it possible to obtain a shaft hole 7 that is not tapered and is coaxial with the shaft hole 3. can. In particular, even if a gap exists between the inner wall surface of the shaft hole 3 of the cylindrical molded product 1 and the outer wall surface of the bush 4,
Since the adhesive 5 acts to fill this gap, the integration of the cylindrical molded product 1 and the bush 4 is promoted, and a cylindrical member having a highly stable and reliable shaft hole 7 is obtained. I can do it. the result,
The shaft (not shown) is completely attached to the shaft hole 7,
It is possible to smoothly unwind the thread, and the life of the thread can be extended. In addition, a 100% inspection to determine whether the taper of the shaft hole 3 is within the standard value is not necessary, and the cylindrical molded product 1 has a taper exceeding the standard value or an irregularly shaped part.
This eliminates the need for internal grinding to correct the problem, reducing man-hours to approximately 1/3.
