Claims

[Claims for Utility Model Registration] (1) In a toothed belt transmission device in which a toothed belt having a tooth profile of the pitch on the inside is hung between first and second external gears having a certain pitch, A toothed belt transmission device characterized in that the first and second external gears are double-edge gears, and the tooth profile of the toothed belt has a chevron shape that meshes with the toothed belt gear. (2) The distance in the circumferential direction from the tip of the tooth of the toothed belt to the rear end of the toothed belt is set longer than the pitch of the tooth of the tooth, and the distance from the tip of the tooth of the toothed belt to the rear end of the toothed belt is The ratio of the circumferential distance to the belt width of the toothed belt is equal to the ratio of the distance from the tip to the rear end of the helical gear of the helical gear and the width of the helical gear, and The toothed belt transmission device according to claim 1, wherein the pitch of the toothed belt is equal to the pitch of the gear teeth of the toothed belt.
