Patent number: 6884192Abstract: In a movable guide for transmission device in which a guide body is formed from a synthetic resin and comprises a chain-contacting shoe and a plate-receiving portion formed as a unit with the shoe on the back side thereof, the plate-receiving portion has plural, longitudinally extending slots, each receiving a reinforcing plate. The plural reinforcing plates improve the bending rigidity, toughness, strength and wear properties of the guide, prevent falling down of the guide and guide torsion, ensure stable travel of the chain, and prevent running of the chain off the guide in a widthwise direction. Improved compactness of the guide and of the overall mechanism, is made possible by the use of plural plates. The plates can be connected to one another by a tensioner-contacting portion, formed as a unit with the plates.Type: GrantFiled: January 13, 2003Date of Patent: April 26, 2005Assignee: Tsubakimoto Chain Co.Inventors: Masahiko Konno, Toshifumi Satoh
