Timing device and manufacturing method for a variable valve of an internal combustion engine

A variable valve timing device for an internal combustion engine includes: a variable valve timing mechanism (30) that changes a valve timing; and a phase limiting mechanism (40) that locks a rotational phase between a housing rotor and a vane rotor at an intermediate phase (PM). The phase limiting mechanism (40) engages a first limiting pin (51) with a first engaging groove (60) and engages a second limiting pin (71) with a second engaging groove (80) to lock the housing rotor to the vane rotor. A retard-side side surface of an engaging hole (83) is configured so as to be able to adjust a clearance between the second limiting pin (71) and the retard-side side surface (83A) when the first limiting pin (51) is engaged with a first advance end portion (62A).
