Abrégé

A CVT(Continuously Variable Transmission) is disclosed, in which a structure is simple, and less volume and weight are obtained, and manufacturing does not cost a lot, and less impact and noise occur during a transmission, and a maintenance does not cost a lot, and a module type transmission can be manufactured. A semispherical unit is used in stead of at least two spherical units like in the conventional at, and an eccentric support unit having a roller which supports a pressing force of a semispherical unit is installed in an opposed contact point of a semispherical unit instead of a pressure plate, and the present invention can be applied to a bicycle as well as various driving means such as motorcycle, an automatic handcart, a spinning wheel or the like without a design change.

Abrégé

The present invention relates to a floor hinge which keeps constant a speed of closing the door, and prevents the hinge from being damaged to make preparation against a failure of an oil pressure. The floor hinge includes: a main body (10); a cylinder (14) having a first spring (12) inside; an anti-deviation cover (16) for preventing the first spring (12) of the cylinder (14) from being deviated; a weight- shaped turning unit (20) disposed at the other corner of the main body (10); a second spring (22) mounted within the turning unit (20); a roller guide (24) for opening or closing a door; an oil guide (26) for aiding the roller guide (24) to slowly turn; and an arc-shaped turning guide (28) disposed along an inner circumferential surface of the main body and aiding the turning unit to turn.
