A positioning and clamping apparatus clamps a panel material by moving a clamp arm to a clamping position while the panel material positioned by a locating pin is supported by a workpiece supporting face of a workpiece support. An extruding member having a plurality of extruding rods protruding from the workpiece supporting face is slidably provided in the workpiece support, and the panel material is detached from the locating pin since the extruding member causes a tip face of the extruding rods to be moved to a carry-out position by the hollow piston. The extruding member is caused to protrude by a spring force up to a standby position located between the carrying-out position and the workpiece supporting position, thereby being pushed down up to the workpiece supporting position by the panel material.
