A folding shelf holder is strong and folds easily. A wall side member has a pin as a rotational axis of a shelf side member relative to the wall side member and a rotation limiter limiting rotation of the shelf side member relative to the wall side member. The shelf side member has a long groove for inserting the pin of the wall side member. When the folded shelf side member is opened to be approximately orthogonal to the wall side member and the shelf side member is slid toward the wall side member and in a direction where the long groove extends, the shelf side member abuts, at a back side of the pin, to the rotation limiter of the wall side member, preventing rotation of the shelf side member relative to the wall side member. Then, the shelf side member cannot fold relative to the wall side member.
