PROBLEM TO BE SOLVED: To provide a valve timing adjusting device that secures startability of an internal combustion engine. SOLUTION: The valve timing adjusting device 1 is accommodated in a vane rotor 14 so as to be reciprocated, regulates a rotation phase in a regulated phase between the most advanced angle phase and the most delayed angle phase by moving in a direction X of entering a recess 134 formed in a housing 11, and has a regulation member 150 that moves in a direction Y for escaping from the recess 134 and releases the regulation for the rotation phase. The housing 11 forms an open hole 137 that is open to the atmosphere. The vane rotor 14 forms a communication hole 147 communicating with an advance chamber 52, and connects the open hole 137 with the communication hole 147 by moving a predetermined member 152 from a position for shutting off the open hole 137 from the communication hole 147.
