Abstract
A positioning mechanism in a positioning and clamping device includes an annular tapered surface that is formed on an outer periphery of a cylindrical shaft for positioning a pallet in the horizontal direction, and has a decreasing diameter toward an axial tip of the cylindrical shaft. An annular engaging mechanism, which is formed on an inner periphery side portion of an annular engagement member, is engageable with the annular tapered surface, and is elastically deformed in the radial direction, as a result of engagement with the annular tapered surface. The engaging mechanism has a tapered ring portion, which makes a face contact with the annular tapered surface, and multiple ribs extending outward, radially, from the tapered ring portion.
