Swing chair

A swing chair comprising:

• a support which is installed at a certain height or more above a floor;
• a main operation member which is elongated and has a virtual first rotation axis provided to the support at one side thereof and which is rotatably coupled to the support;
• a sub operation member which is elongated and has a virtual second rotation axis, provided to the support at one side thereof and spaced parallel to the first rotation axis, and which is rotatably coupled to the support;
• a seat portion coupled to any one of the main operation member and the sub operation member;
• and
• a rotation connecting member which is elongated and arranged in a front-rear direction and has a rear portion that is rotatably coupled to the other side of the main operation member and a front portion that is rotatably coupled to the other side of the sub operation member so that a closed virtual quadrangle is formed together with the support, the main operation member, and the sub operation member,
• wherein an angle of coupling between the rotation connecting member and the main operation member is changed according to user's operation and the main operation member is interlocked with the virtual quadrangle and swings forward and backward based on the first rotation axis,
• wherein a portion of the rotation connecting member protrudes forward in a longitudinal direction,
• wherein the rotation connecting member is adjusted in a state in which a user is seated in the seat portion, and
• wherein a separate operation handle is provided in front of a point of coupling between the rotation connecting member and the sub operation member, so that the rotation connecting member is arranged at a position where the user approaches the rotation connecting member while being seated in the seat portion.
