Claims

[Scope of utility model registration request]

In a wiper blade joint structure in which levers of wiper blades are connected to each other or a yoke to which a blade rubber is attached and a lever are connected via a spacer, the spacer protrudes outward to engage with the primary lever or the secondary lever, and the primary a first engaging portion that locks the lever or the secondary lever; a second engaging portion that protrudes inward and engages the secondary lever or yoke to lock the secondary lever or yoke; and both of the engaging portions. A joint structure for a wiper blade, characterized in that it is provided with a flexible portion that is bent inward and outward directions to facilitate engagement with the lever or yoke.
