Abstract
To achieve a mechanism that supports an article at a desired position in a displaceable manner in accordance with a weight of the article with a simple, small, and lightweight structure.An article supporting device 1 includes a base member 2, a supporting member 3, a spring member 4 which is a compression coil spring, a spring force transmission member 5, a cam member 6, and a cam follower member 7. The cam follower member is pressed against a downward-facing cam surface 15 of the support member, an upward-facing cam surface 18 of the spring force transmission member, and a sideward-facing cam surface 22 of the cam member by a load of an article and a spring force of the spring member. The downward-facing cam surface and upward-facing cam surface are inclined in reverse directions to each other and disposed opposite to each other with the cam follower member interposed therebetween. A pressing force of the sideward-facing cam surface against the cam follower member includes a vertical direction component depending on a height position of the supporting member. The downward-facing cam surface, upward-facing cam surface, and sideward-facing cam surface are designed such that, in a mo…
