で固めたもの等を材料として構成する。 What is shown in Figures 4a and 4b is the operating section for turning on the vacuum switchgear (see Figures 1 and 2), and the reference numeral 15 in the figure is the operation that is not shown. This is an operating lever that is operated by the device to close the vacuum opening/closing device, and is made of, for example, an insulating member. 16a indicates a fulcrum bearing part provided integrally with the insulating frame 16,
It is configured to freely support a protrusion 15a provided on the operating lever 15. The engagement portion of the fulcrum bearing portion 16a with the protrusion 15a is formed into an appropriate recess (approximately V-shaped in the embodiment) 16b, and this recess 16b is made of a material different from that of the protrusion 15a. A formed bearing member 17 is mounted. Therefore, the protrusion 15a and the bearing member 1
The engaging portion 18 with the locking portion 7 serves as an operating fulcrum for the operating lever 15, and the operating lever 15 is rocked about the engaging portion 18 to perform the closing operation. The bearing member 17 is made of wear-resistant plastic,
That is, fluororesin (Teflon - registered trademark),
The material is made of acetal copolymer containing fluororesin (Dyuracon - registered trademark) or glass fiber hardened with resin.

ある。 According to the above configuration, since both the engaging members in the engaging portion 18 are made of different materials, wear of the both engaging members can be reduced. In addition, since a soft material and a rigid material are used as both engaging members as described above, the surface of the soft material at the joint portion 18 conforms to the surface of the hard material, and the soft material side mainly absorbs damage. Therefore, the wear resistance of the hard material side is improved, and the time required to replace the engaging portion 18 can be lengthened. Therefore, the life of the switchgear as a whole can be extended and its reliability can be improved. Further, the bearing member 17 has a V-shaped recess 16.
b, the shape is simple and manufacturing is easy. Furthermore, if the bearing member 17 is worn out or damaged during assembly, it is only necessary to remove and replace the bearing member 17, which improves the workability of the replacement work and is economically advantageous.

The bearing member 17 is removably attached to the operating lever 15 through the fulcrum bearing portion 16a.
It is constructed so that it can be attached to and detached from it. For example, the fulcrum bearing part 16a is made of a suitable metal, the bearing member 17 is made of a steel member, and the fulcrum part 15a is made of a sintered alloy or the like. With this structure, it is possible to withstand large loads acting on the fulcrum part or frequent loading and shearing operations, and the engagement part 18 of the fulcrum part is able to withstand wear. Sometimes they can be easily replaced. Further, when using an expensive material for the fulcrum portion 15a, an expensive fulcrum member 15b may be fixed to the tip portion, as shown in Figure c.
