A belt length adjuster includes a frame body (1) with two outer frames (1a, 1a) and two connecting frames (1b, 1b), and a support frame (2) provided between the two outer frames (1a, 1a) stretching to and between the two connecting frames (1b 1b). The support frame (2) supports one end part (B1) of the belt member (B) to be used with the belt length adjuster. Two inner frames (1c, 1c) are respectively provided between the support frame (2) and the respective outer frames (1a, 1a) stretching to and between the two connecting frames (1b, 1b). The support frame (2) and the respective inner frames (1c, 1c) provide insertion spaces (Sa, Sa) therebetween into which the one end part (B1) of the belt member (B) is inserted, while the respective inner frames (1c, 1c) and the respective outer frames (1a, 1a) provide insertion spaces (Sb, Sb) therebetween into which the other side (B2) of the belt member (B) is inserted. Easy and instant adjustment of the belt length is achieved. The adjuster can be made easily and at low cost. Furthermore the one end part (B1) of the belt member (B) is easily attached to the support frame (2). |
