A valve opening and closing timing control apparatus comprising: a driving side rotor that synchronously rotates with a crankshaft of an internal combustion engine; a driven side rotor that is disposed coaxially with the driving side rotor and synchronously rotates with a camshaft of the internal combustion engine; a fluid pressure chamber that is formed on at least one of the driving side rotor and the driven side rotor, and is partitioned into an advance angle chamber (Ca) and a retard angle chamber (Cb); a bolt member that is disposed coaxially with a rotary axis of the driven side rotor, connects the driven side rotor and the camshaft, and is provided with a cylindrical portion coaxial with the rotary axis; a partition body that is provided with a press-fit portion press-fitted into the cylindrical portion, and partitions the cylindrical portion into a first flow passage and a second flow passage for use for supplying and discharging working fluid to and from the fluid pressure chamber; a valve body that opens and closes the first flow passage; and a valve housing body that accommodates the valve body, wherein an engaging portion which has a smaller diameter than that of the press-fit portion is provided on the first flow passage side of the press-fit portion, and the valve housing body is provided with an engaged portion which is externally fitted to the engaging portion, wherein the engaged portion is provided with an abutting portion which abuts on the cylindrical portion and a space is formed which functions as a foreign matter reservoir between the engaged portion and the cylindrical portion, and closer to the press-fit portion side than the abutting portion. a driving side rotor that synchronously rotates with a crankshaft of an internal combustion engine; a driven side rotor that is disposed coaxially with the driving side rotor and synchronously rotates with a camshaft of the internal combustion engine; a fluid pressure chamber that is formed on at least one of the driving side rotor and the driven side rotor, and is partitioned into an advance angle chamber (Ca) and a retard angle chamber (Cb); a bolt member that is disposed coaxially with a rotary axis of the driven side rotor, connects the driven side rotor and the camshaft, and is provided with a cylindrical portion coaxial with the rotary axis; a partition body that is provided with a press-fit portion press-fitted into the cylindrical portion, and partitions the cylindrical portion into a first flow passage and a second flow passage for use for supplying and discharging working fluid to and from the fluid pressure chamber; a valve body that opens and closes the first flow passage; and a valve housing body that accommodates the valve body, wherein an engaging portion which has a smaller diameter than that of the press-fit portion is provided on the first flow passage side of the press-fit portion, and the valve housing body is provided with an engaged portion which is externally fitted to the engaging portion, wherein the engaged portion is provided with an abutting portion which abuts on the cylindrical portion and a space is formed which functions as a foreign matter reservoir between the engaged portion and the cylindrical portion, and closer to the press-fit portion side than the abutting portion.
