Claims

[Scope of Claim for Utility Model Registration] (1) The base end of a brake lever, one end of which is formed as a free end, is pivotably attached to an armrest that constitutes a part of the chair, and the pivot On the opposite side, the upper end of the brake operating rod, which is a rod-shaped body that is constantly biased downward by a spring or other force, is fitted and locked, and the lower end of the brake operating rod is fitted with the wheel. A brake mechanism for an infant chair configured to connect a locking rod for brake operation that restricts the rotation of the child's chair by abutting or locking the rod. (2) The braking mechanism for a child's chair according to claim (1), wherein the child's chair is configured to be foldable. (3) A fitting hole is drilled near the free end of the brake lever whose base end is pivotally connected, for fitting and locking the upper end of the brake operating rod so that it can swing freely. A brake mechanism for an infant chair as set forth in claim (2) of patent registration. (4) Utility model registration claim paragraph (2) or (3) in which the fitting groove split near the free end of the brake lever is formed in an inverted L-shape. Brake mechanism of infant chair as described in Section 1. (5) The brake mechanism for a child's chair according to claim (1) of the utility model registration, wherein the child's chair is configured so that it cannot be folded. (6) The braking mechanism for an infant chair according to claim (5), wherein the fitting hole of the brake operating rod formed near the free end of the brake lever is a circular transparent hole.
