ABSTRACT:
A link mechanism prevents a first pin from coming out of a groove and prevents interference with other elements. The line of action is the line orthogonal to the center line of the grooved portion and passes through the center of the first pin when the first pin is located at the open end of the grooved portion. A reference line passes through the swinging center of the first link lever and the center of the first pin. The angle between the line of action and the reference line is larger than 0°. The force that raises the pressure at the contact surface between the second pin and the cam surface acts upon the first pin from the grooved portion when the first pin is located at the open end of the grooved portion. The link mechanism is operational without the cam grooved wall in the entire cam surface region.
