A valve timing varying device includes a housing rotor (20) composed of a front side housing member (22) and a rear side housing member (21), a vane rotor (30), and an urging spring (40) for rotationally urging the vane rotor in one direction with respect to the housing rotor. The urging spring has a coil part, a first end provided outside in a radial direction with respect to the coil part, and a second end provided inside in the radial direction with respect to the coil part. The front side housing member has a first latching concave part for latching the first end on an inside wall face. The vane rotor has an accommodation concave part for accommodating at least a part of the coil part at the front end side, and a second latching concave part for latching the second end in an area facing an opening.
