V-BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION

To suppress enlargement of a V-belt by a simple constitution.SOLUTION: A belt regulation member (200) of a V-belt type continuously variable transmission (71) comprises arm parts (201 and 201X) which extend in the direction of crossing a reference plane (M1) connecting axis lines of a pair of pulleys (80 and 90), and first and second abutting parts (202 and 203) which are positioned on the outer peripheral sides of the V-belt (75) with the reference plane (M1) in between, respectively, and which are supported by the arm parts (201 and 201X). When either of the V-belts (75) positioned on both sides with respect to the reference plane (M1) moves to the side of separation from the reference plane (M1) and abuts on one of the first and second abutting parts (202 and 203), this abutting force makes the arm parts (201 and 201X) move, and the other one of the first and second abutting parts (202 and 203) pushes the V-belt (75) on the side opposite to the reference plane (M1) to the side of the reference plane (M1).SELECTED DRAWING: Figure 4 【課題】簡易な構成で、Ｖベルトの拡がりを抑制すること。【解決手段】Ｖベルト式無断変速機（７１）のベルト規制部材（２００）は、一対のプーリ（８０，９０）の軸線を結ぶ基準面（Ｍ１）に対し、交差する方向に延出するアーム部（２０１，２０１Ｘ）と、基準面（Ｍ１）を挟んで、Ｖベルト（７５）の外周側にそれぞれ位置し、アーム部（２０１，２０１Ｘ）に支持される第１当接部（２０２）及び第２当接部（２０３）とを備え、基準面（Ｍ１）に対して両側に位置する前記Ｖベルト（７５）のいずれかが、基準面（Ｍ１）から離れる側に移動し、第１当接部（２０２）及び第２当接部（２０３）の一方に当接すると、この当接力によりアーム部（２０１，２０１Ｘ）が移動し、第１当接部（２０２）及び第２当接部（２０３）の他方が、基準面（Ｍ１）に対して反対側の前記Ｖベルト（７５）を基準面（Ｍ１）側に押圧する。【選択図】図４
