To provide a support mechanism between elements, a tool changing device, a conveying device and an actuator capable of pressing a ball against a machine element even if the ball diameter cannot be adjusted precisely and a gap is generated between the ball and the machine element thereby capable of connecting the machine elements organically without causing malfunction of wobbling and the like.
The support mechanism between elements 70 of the invention comprises a spherical body 42 installed between a first element 3 and a second element 120 one of which is movable against the other and capable of supporting the first element 3 and a pressing means capable of pressing the spherical body 42 against the first element 3.
