Abstract: A stabilizer device 1 includes a bar 100 having a portion 10a to be mounted to a vehicle body. A resin ring 40 is integrally formed to the bar 100 by a direct injection method, and a bush 30 made of rubber is provided around the periphery of the resin ring 40. The bush 30 is fixed to a member 50 of the vehicle body side by a bracket 20. Since the contact area of the resin ring 40 to the bar 100 is secured by using the axial direction length of the bush 30, the movement strength of the bush 30 in the axial direction can be improved even when there is size restriction. In the fixing construction of the stabilizer device, the movement of the bush to the bar can be sufficiently prevented even when the size restriction is severe.
