Abstract
The valve timing changing device includes a vane rotorthat rotates integrally with a camshaft around an axis S of the camshaft and includes a lock pin; and a housing rotor Hr that is rotatable relative to the vane rotor around the axis within the range of a predetermined movable angle Δθ and whose relative rotation is locked by the lock pin. The housing rotor Hr includes a toothed memberhaving a tooth rowto which a driving force is applied, and a bottomed cylindrical housing memberfixed to the toothed member and accommodating the vane rotor. The housing memberis formed with a center of gravity eccentric from the axis S on a side that relatively reduces an imbalance amount mof the vane rotor.
