The valve timing varying device according to the present invention 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 (40) has a coil part (41), a first end (42) provided outside in a radial direction with respect to the coil part, and a second end (43) provided inside in the radial direction with respect to the coil part. The front side housing member (22) has a first latching concave part (22f) for latching the first end on an inside wall face. The vane rotor (30) has an accommodation concave part (35) for accommodating at least a part of the coil part at the front end side, and a second latching concave part (36) for latching the second end in an area facing an opening (22c). Therefore, wear and a friction force in a sliding area can be reduced and the assembling performance can be improved while achieving the size reduction of the device. |
