Abstract
First and second recessed portions are respectively formed on first and second wall surfaces of a cam chamber, in order that a plunger head and a coil spring would not come in touch with the first and second wall surfaces even in such a virtual situation. In the virtual situation, it is supposed that the plunger head would be separated from a plunger, the plunger head remains in contact with a contact surface of a cam ring so that the plunger head would not move relative to the contact surface, and a cam member would be continuously rotated.
