Abstract: A belt length adjuster includes a frame body with two outer frames and two connecting frames, and a support frame provided between the two outer frames and stretching to and between the two connecting frames. The support frame supports one end part of the belt member to be used with the belt length adjuster. Two inner frames are respectively provided between the support frame and the respective outer frames and stretching to and between the two connecting frames. The support frame and the respective inner frames provide first insertion spaces into which the one end part of the belt member is inserted, while the respective inner frames and the respective outer frames provide second insertion spaces into which the other side of the belt member is inserted. Furthermore the one end part of the belt member is easily attached to the frame body.

Abstract: Goggles include an eye-cup and a belt that are coupled by means of a coupling member. The eye-cup and the coupling member can be engaged and disengaged easier compared with conventional goggles. In the goggles, at a connecting end of the coupling member is provided an elastic bent piece with a V-shape section and a spring property. And a connection recess is provided on the eye-cup. The elastic bent piece of the coupling member and the connection recess of the eye-cup are fixed together in a mutual engaging state. The engaging state can be released by narrowing the gap distance in the V-shape of the elastic bent piece.
