Dependent claims

A linking mechanism for linking a plurality of chairs;

the plurality of chairs being aligned in a left and right direction;
the linking mechanism comprising a portion configured to receive at least a part of a leg of a chair;
a surface configured to abut a floor surface, and configured to support the chair on the floor surface, and a convex linking member and a concave linking member, the convex linking member and the concave linking member being engaged with each other thereby to realize linkage of the plurality of chairs,
wherein the convex linking member includes:
a convex-side mounting portion which is provided to one of left and right side regions in a first chair of the plurality of chairs;
an extending portion which extends in a direction from the convex-side mounting portion toward a second chair of the plurality of chairs;
a notch portion which notches a region reaching from a front end region of the extending portion to a side of the convex-side mounting portion, thereby to divide the extending portion into two parts in a front and back direction;
and
an engaging piece which projects along the front and back direction from one or both of front end sides of the two parts into which the extending portion is divided by the notch portion, and
wherein the concave linking member includes:
a concave-side mounting portion which is provided to the other of the left and right side regions of the second chair of the plurality of chairs;
an engaging projection which projects from the concave-side mounting portion to a direction toward the first chair of the plurality of chairs and engages into the notch portion in the convex linking member;
and
a pair of engaging wall portions between which the engaging projection is located, and each of which function as a wall that surrounds one of the two parts into which the extending portion is divided and the engaging piece in the surrounded part of the extending portion in the convex linking member.
