Claims

[Scope of utility model registration request]

Rotatably relative to the fixed board fixed to the cover 2
A so-called resin-made ring consisting of a pair of substantially arc-shaped ring pieces protruding from four locations, which form a ring by fixing two rotating boards and locking their tips to each other on the fixed board and the rotating board, respectively. In a 4-hole ring binder, a hinge ring is formed in which the fixed base plate and the rotary base plate are attached to each other with appropriate openings in the upper and lower directions, and a locking hole is formed in one of the pair of ring pieces in the other. A locking protrusion is provided to lock the binder, and the two rotating substrates are fixed to the fixed substrate with a spring interposed so as to slide appropriately toward the center of the binder, and the two rotating substrates face each other at the center. 1. A four-hole ring binder, characterized in that by squeezing the ring pieces inward, the locking state of the rings at the four locations is released and the rings are expanded.
