Next, the attachment base portion 22 of the clip 2 is attached to the attachment convex portion 31 of the decorative member 3 attached to the rear end portion of the cylindrical body 1. Specifically, the mounting convex portion 31 is inserted into the mounting base portion 22, and the engaging pieces 23 are inserted and engaged with the engaging grooves 32 on both side surfaces of the mounting convex portion 31. At this time, the second mark 6 is disposed radially inward of the clip body 21 and in the vicinity of the attachment base 22 of the clip 2. Thereby, when the clip 2 is viewed from the front, the second mark 6 is concealed by the clip 2, the second mark 6 becomes invisible from the outside, and the appearance of the cylinder 1 having the pattern 4 is not impaired. .
