As shown in FIG. 5, the facing surfaces of the eyecup 2 and the closing wall 7 are formed in an arcuate surface 10 with the projecting shaft 9 as the center, and the buckle connector 6 swings along the arcuate surface 10. It is free.

As shown in FIG. 3, a buckle insertion hole 11 is formed in the closing wall 7 of the buckle connector 6, and a plate-shaped buckle 12 is slidably inserted into the buckle insertion hole 11.

A belt insertion hole 13 is formed at an outer end portion of the buckle 12 located outside the buckle connector 6, and an end portion of the elastic belt 14 is inserted into the belt insertion hole 13 from the inner surface side of the buckle 12. There is.

An end portion of the elastic belt 14 projecting to the outer surface side of the buckle 12 is folded back in a direction overlapping with the surface of the elastic belt 14, and a belt pressing piece 15 for pressing the folding belt 14 a against the buckle 12 is outside the closing wall 7. It is provided on the end face.

The belt pressing piece 15 is adapted to press the folding belt 14a against the buckle 12 when the buckle 12 is pushed into the belt connecting hole 5.
The buckle 12 is stopped and held while the belt pressing piece 15 presses the folding belt 14a. Further, the buckle 12 is prevented from slipping out of the buckle insertion hole 11 when the belt insertion hole 13 is located outside the belt pressing piece 15.

As a holding means and a retaining means for the buckle 12, an inclined elastic piece 16 is integrally provided at an inner end portion of the buckle 12 located inside the belt connecting hole 5, and the elastic piece 16 has an end portion. The buckle 12 is held at the pushed position by the engagement of the circular operation button 17 formed and the circular engagement hole 18 formed on the outer surface of the outer end portion of the eyecup 2. Further, the buckle 12 is prevented from coming off by the contact of the operation button 17 with the inner surface of the closing wall 7.

The engagement hole 18 is formed coaxially with the projecting shaft 9 so as not to interfere with the swing of the buckle connector 6.

The belt connecting device shown in the embodiment has the above-mentioned structure, and when adjusting the length of the elastic belt 14, the operation button 17 is pushed in and the buckle 12 is removed while the engagement with the engagement hole 18 is released. Direction, and the operation button 17 is brought into contact with the inner surface of the closing wall 7 to position the belt insertion hole 13 outside the belt pressing piece 15 (see FIG. 4). In that state, the elastic belt 14 is pulled to adjust the length of the elastic belt 14.

At this time, since the elastic belt 14 is inserted into the single belt insertion hole 13, the contact resistance to the inner circumference of the belt insertion hole 13 is extremely small, and the elastic belt 1
