[Prior Art] 5 A conventional bicycle chain mainly includes a plurality of two-two slabs, and a plurality of two-two Inwardly located between each outer link plate 成 多数 a plurality of bushings disposed in pairs between each pair of inner link plates, more than slidably sleeved on each bushing The roller, wherein each of the inner chain plates and the two inner perforations respectively correspond to one end of the adjacent two outer chain plates, and the two ends of each of the two axial holes correspond to the inner perforations of each pair of inner chain plates. Thereby, the j-pin is inserted through the through hole outside the outer key plates, the inner hole plate and the inner hole plate and the bushing shaft hole for the outer chain plate, the inner chain plate and the bushings There is also a bushing-free bicycle chain, which differs from the above-mentioned bicycle chain 15 in that the inner perforations (2) on the inner side of the inner chain plate (1) are formed in two, as shown in the first figure. The outer peripheral surface of each of the flanges (3) is provided for the respective roller sleeves', and the inner circumferential surface of each of the flanges (3) is provided for the respective plugs to abut. 20 For the design of the above two kinds of bicycle key strips, each roller must be axially sleeved on the outer circumferential surface of each bushing or each flange, and each bushing or each of the 'same must' (four) shaft sleeves ^ Each plug, so that the size of each plug will roll: is limited to match the design of the nest. Moreover, when the bushing is in the socket, a gap is inevitably generated between each other, so that when the bicycle key is actuated, a necessary vibration or movement between the bushing and the roller is caused to cause instability of the overall structure. 4 200930919 [Description of the Invention] The purpose of the invention is to provide a bicycle key bar, which has a strong structural strength and good stability. The purpose of the invention is to provide a bicycle that has a light weight. ❹ 15 ❹ In order to achieve the above object, the bicycle chain provided by the present invention comprises a plurality of outer chain plates, a plurality of inner key plates, a plurality of sets, and a plurality of connectors. Each of the two ends of the outer link plate has an outer perforation; each pair of inner key plates is located between each of the outer link plates, and each of the inner link plates has an inner perforation, and each of the inner plates has a perforation Corresponding to the outer perforations of the adjacent two outer link plates respectively; the bushings are disposed in pairs between each pair of inner key plates, and the miscellaneous sleeves respectively have a shaft hole, and the shaft holes respectively The two ends respectively correspond to the perforations in each of the pair of plates; the connecting members are respectively disposed through the perforations outside each of the outer key plates, the perforations in each of the pair of ply plates, and the axial holes of each of the sets of the sets The end of the piece is engaged with the outer perforation of one of the outer link plates, and the other end of each of the connecting pieces is connected with the outer perforation of the other outer link plate. Thus, the present invention forms the flange at one end of each of the connecting members, and the flange 20 is engaged with the peripheral edge of the outer peripheral plate by the flange, so that the connecting members can be increased in size to assist in supporting the bicycle. The external force experienced by the chain is used to enhance the overall structural strength of the present invention. Moreover, after the size of each of the connectors is increased, the interior can be hollowed out to reduce the weight of the bicycle chain. 5 200930919 [Embodiment] In order to explain the structure, features and functions of the present invention in detail, the following preferred embodiments are described with reference to the accompanying drawings, wherein: The second drawing is a perspective view of a first preferred embodiment of the present invention; the fourth drawing is a partial cross-sectional view of a first preferred embodiment of the present invention; and the fifth drawing is a second preferred embodiment of the present invention. 3 is an exploded perspective view of a third preferred embodiment of the present invention; and a seventh partial cross-sectional view showing a third preferred embodiment of the present invention.
