Provided is a rocking chair having a seat body for a user to sit on, a support body for supporting the seat body from below, and a connecting mechanism provided between the seat body and the support body to move the seat body along a surface of a sphere centered on a base point above the seat body in response to an external force applied to the seat body. The connecting mechanism is composed of at least three sub-mechanisms, each of which has a circular track section on the support body side, a linear track section on the seat body side, and a connecting section to interlock their movements. The circular track section has a first traveling member and a first guiding member for traveling the first traveling member along a circle. The linear track section has a second traveling member and a second guiding member to make the second traveling member travel along a surface of a concentric sphere centered on the base point and in a linear manner when viewed from a direction parallel to a central axis of the circle wherein the first traveling member travels. The connecting section has a connecting member that is connected at both ends to a first retainer that holds the first traveling member and a second retainer that holds the second traveling member, and at least one of the first retainer and the second retainer is rotatably connected to the connecting member.
