PROBLEM TO BE SOLVED: To provide a connecting structure for struts of a display implement which can turn and hold the struts at a prescribed angle, is simple in connection and is good in operability. SOLUTION: Since respective bulging parts 8 and 17 of the respective struts 6 and 15 and annular recessed surfaces 27a and 27b of a connecting pipe shaft member 21 fit each other, the struts are not easily removable. Outer peripheral surfaces 9a, 9b, 18a and 18b adjacent to each other of approximately regular octagonal shaft parts of the struts 6 and 15 and joint surfaces 28a, 28a, 28b and 28b of the connecting pipe shaft member 21 are joined to each other and therefore if the strut 15 and the connecting pipe shaft member 21 are relatively turned, friction resistance increases before the angle parts greater in the radius than the outer peripheral surfaces rub the joint surfaces and pass by the same, by which a moderation effect is generated. Detent legs 10 and 10 at the front end face of the strut 16 are engaged with engaging recessed grooves 31 of a bottom 29, by which the relative turning of the strut 6 and the connecting pipe shaft member 21 is prohibited.
