Title:
BICYCLE CHAIN AND TRANSMISSION SYSTEM COMPRISING THE CHAIN
Document Type and Number:
Japanese Patent JP2017105438
Kind Code:
A
Abstract:
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
