Abstract

To provide a positioning structure that allows an attachment member to be easily attached to a desired position on a ball chain.SOLUTION: A positioning structure is provided on an inner lid 30 constituting a washing tank 1 as a component constituting a toilet member. The positioning structure is structure for attaching an attachment member 55 to a predetermined position on a ball chain 52. The positioning structure comprises a first positioning part 31 and a second positioning part 32. The first positioning part 31 positions an upper end side as one end of the chain 52. The second positioning part 32 positions the attachment member 55 at a predetermined distance away from the first positioning part 31.SELECTED DRAWING: Figure 6
