PROBLEM TO BE SOLVED: To provide a lock hinge for which frictional resistance between a bearing portion and a shaft lever can be set constantly and the frictional resistance between the bearing portion and the shaft rod can be easily changed. SOLUTION: A space member 4 is interposed between collar plate portions 3, 3 arranged closely at the outer side of an opening edge of an opening portion 2 in a longitudinal direction provided at a cylindrical bearing portion 1, both collar plate portions 3, 3 are tightened and fixed and a shaft lever 5 is supported by the bearing portion 1 in a rotatable manner with a resistance given to the shaft rod 5. In this way, a tightening force of both the collar plate portions 3, 3 by the space member 4 is restricted, the opening width of the opening portion 2 becomes constant, and the frictional resistance between the bearing portion 1 and the shaft lever 5 can be made constant. Also, the frictional resistance can be easily changed by changing the space member 4 thereby corresponding to a door having a different weight, lap-top type display or the like.
