PROBLEM TO BE SOLVED: To provide a joint structure of a cleaner which can attain a stable connecting state between a cleaning head and a connecting member by enough securing the insertion length of a pin projection of the connecting member into a pin hole in a simple constitution.SOLUTION: A pin hole 23 is formed in each of opposite surfaces 17b disposed at a space of a pair of yoke projecting parts 17a constituting a head side yoke part 17. A connecting member 19 includes a pair of unit connecting members 20, and the respective unit connecting members 20 are rotatably inserted in the respective pin holes 23 of the pair of yoke projecting parts 17a. The joint structure includes a pin projection 21 as a first turning shaft center part 19a, and includes overlapping engagement surfaces 22a, 22b overlapped in a part between the pair of yoke projecting parts 17a. With the overlapping engagement surfaces 22a, 22b overlapped with each other to integrate the pair of unit connecting members 20 with each other as the connecting member 19, a second turning shaft center part 19b is disposed above the part between the pair of yoke projecting parts 17a. |
