(Effects of the invention) The temple of the glasses of the present invention has a structure in which the front temple and the rear temple are integrated through the locking part, the connecting piece part, and the set screw, so that the temple of the glasses after the replacement of the rear temple and the temple after the replacement are fixed. You can easily adjust the length. Therefore, for example, by replacing a rear temple with a half-hook type ear hook part with a rear temple with a cable type ear hook part, it is possible to use it during sports that involve strenuous movements such as golf or tennis, or during various sports that involve strenuous movements. When working, it is possible to avoid inconveniences such as glasses slipping off or falling off during activities. In this way, the purpose of the glasses can be changed by simply replacing the rear temples, which is not only very economical compared to carrying two types of glasses as in the past, but also allows you to carry only the temples when not in use. Therefore, it is more convenient than carrying unused glasses as in the past. Furthermore, by preparing a plurality of rear temples with different designs, the design of the temples can be changed according to one's clothes or mood, thereby improving the fitability of the glasses.

Since the first engaging portion and the second engaging portion are formed as recesses or protrusions that fit into each other, the joint piece portion is locked to the locking portion only at a predetermined position. Therefore, when adjusting the length of the temples after replacing the rear temples, the lengths of the left and right temples can be easily made equal.

Moreover, the exposed joint piece part that has come off the locking part,
Even when the length is at its maximum, at least the outer side of the vine is covered by the cover portion, so that the vine has a continuous, unified appearance and does not look unnatural. Furthermore, it is possible to diversify the temple designs depending on the shape of the cover portion. In addition, when the outer surface of the front end portion of the rear temple is brought into contact with the inner surface of the cover part, the cover part acts as a reinforcing member that resists the outward expansion and deformation of the rear temple when wearing glasses. The stability of the joint between the front and rear temples can be particularly excellent.
