In addition, since the shield temples 38 and 40 on both the left and right sides are deformed according to the size of the head or face of the user M by elastically opening the U-shaped portions, the shield temples 38 and 40 can be adapted to the head or face of various sizes. In addition, the head can be held between the nose hanging part 24 and the ear hanging parts 26, 28 and stably worn. In addition, since the lower portions of the left and right shield temples 38 and 40 can be brought into contact with the cheeks of the user M, it is difficult for the mounting portion 16 to move vertically. Therefore, the connecting portion 18, the shield support portion 14 and the shield portion 12 as a whole can be easily rotated by the force of the user M's hand. Of course, the lower portions of the left and right shield temples 38 and 40 may be configured to be separated from the cheeks of the user M so as not to come into contact with each other. Also, the left and right shield temples 38, 40 may be made of a rigid body whose U-shaped portions are not elastically deformed.

The cylindrical fitting projections of the left shield temple 38 and the right shield temple 40 are inserted into the cylindrical fitting holes 48 (FIG. 3) of the left ear hooking portion 26 and the right ear hooking portion 28 shown in FIG. 46 (FIG. 3) are fitted together, the orientation of the left and right ear hooks 26 and 28 can be easily adjusted by rotating them.
