Valve opening and closing timing control device

A valve opening and closing timing control device includes: a driving-side rotating body coaxial with a rotational axis and rotated in synchronization with an internal combustion engine crankshaft; a driven-side rotating body coaxial with the rotational axis and integrally rotated with a valve opening and closing cam shaft; a connecting member screwed into the cam shaft for connecting the driven-side rotating body to the cam shaft and having a pump port to which a fluid is supplied, an advance angle port communicating with an advance angle chamber, and a retarded angle port communicating with an retarded angle chamber; a spool accommodated within a space of the connecting member to reciprocally move between advance angle, neutral, and retarded angle positions along the rotational axis; and an actuator causing a pressing force to act along rotational axis and operates the spool to be in the neutral, advance angle, or retarded angle positions.
