ABSTRACT:
The ends of a stem on which a number of beads are rotatably and slidably mounted are supported by support members provided on a baby walker. The support members are each formed with a support hole having a small diameter portion and a large diameter portion which differ in inner diameter. After the ends of the stem are inserted from the small diameter portion side, a bulge is formed on each end of the stem. Thus, the stem is fitted in the small diameter portions and the bulges are grasped by the large diameter portions, so that there is no possibility of the stem slipping off the support holes. Further, there is no possibility of the bulges on the stem being exposed outside the support members.
