Abstract: 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.

Abstract: A rocking chair (1) is provided with a seat (30), a projecting member (40) provided on the lower side of the seat (30) and having a convex surface (41a) forming a part of a spherical surface (b) centered on a point (A) located above the seat (30), swivel casters (20) in contact with the convex surface (41a) of the projecting member (40) and guiding the projecting member (40) such that the projecting member (40) can rock along the spherical surface (b), and a support member (10) for the chair. The swivel casters (20) are mounted such that the axes (a) of swivel shafts (22) of the swivel casters (20) pass through the center point (A) of the spherical surface (b), and the seat (30) is guided in the direction of a force applied by rollers (25) of the swivel casters (20). Rocking of the projecting member (40) is smoother than that in rocking chairs using ball casters instead of the swivel casters (20), and noise caused by rocking is drastically reduced.
