PROBLEM TO BE SOLVED: To improve the manufacturing process of a pattern display. SOLUTION: A support 10 comprises two parts of a hub-side part 20 and a free-side part 30. Both of the parts 20 and 30 are connected by engaging of the engaging recess part 18a of a hub-side bridge 18 and the engaging protrusion 28a of a free-side bridge 28 with each other. Thus, it is extremely easy and accurate to match a distance and axes between rings in the case of assembling, particularly in the case of mounting a pattern belt. Furthermore, the pattern belt is not formed of a strong member, it is not necessary to thicken the pattern belt, thereby thin thickness and a light weight are realized. As the result, the inertial mass of the outer periphery part of the pattern display body is reduced and a load onto a motor 35 in the case of acceleration, braking or stopping is reduced, thereby the motor 35 can be miniaturized. Since the pattern display body has divided structure, the structure of a molding die can be simplified and costs for molding is also reduced. COPYRIGHT: (C)2003,JPO
