Patent number: 11940047Abstract: To provide a simple-structured chain guide assembly frame capable of reliably maintaining a correct positional relationship between a driven sprocket and a sprocket holding portion without the possibility of driven sprocket detachment. The chain guide assembly frame includes a main body having a fixed-guide-side sprocket holding portion and a pivoting-guide-side sprocket holding portion. The fixed-guide-side sprocket holding portion includes a first fixed-guide-side support portion that supports a driven sprocket at a first contact point, and a second fixed-guide-side support portion that supports the driven sprocket at a second contact point located more outside than the first contact point. When the driven sprocket is in an erected state in which the driven sprocket is supported at the first contact point and second contact point, the vector of gravity acting on the gravity center of the driven sprocket points between the first contact point and second contact point.Type: GrantFiled: December 13, 2022Date of Patent: March 26, 2024Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Sung-Hwan Lim, Munehiro Maeda, Yuji Oshima
