PROBLEM TO BE SOLVED: To reduce a distance between outer surfaces of an outer plate of a chain without compromising a structural strength.SOLUTION: A bicycle chain is provided that has an alternate succession of outer links (120) and inner links (130) connected to each other at respective end portions thereof (120a, 130a). In the bicycle chain, each outer link and inner link comprises two respective plates (121, 131) parallel to and spaced apart from one another to define a housing space (120c, 130c) for a tooth of a sprocket or toothed wheel. Each plate (121) of each outer link (120) has, at a central portion (120b) thereof, a first thickness. Each plate (131) of each inner link (130) has, at a central portion (130b) thereof, a second thickness. Each plate of each outer link (120) and inner link (130) has, at the respective end portions (120a, 130a), a third thickness that is less than the sum of the first thickness and second thickness.SELECTED DRAWING: Figure 5

    【課題】構造強度を損なうことなく、チェーンの外側プレートの外側表面間の距離を減らすこと。【解決手段】交互に連続する、端部と端部(120a,130a)が互いに連結された外側リンク(120)と内側リンク(130)を備えた自転車チェーンにおいて、外側リンクと内側リンクの各々が、平行かつ互いに離間し、スプロケットまたは案内歯車の歯を収納するスペース(120c,130c)を形成する2つのプレート(121,131)を備え、各外側リンク(120)の各プレート(121)は中央部(120b)に第1の厚さを有し、各内側リンク(130)の各プレート(131)は中央部(130b)に第2の厚さを有し、外側リンク(120)と内側リンク(130)各々のプレートは、前記端部と端部(120a,130a)で第3の厚さを有し、第3の厚さは第1の厚さと第2の厚さの和よりも小さい。【選択図】図5
