Document Type and Number:
WIPO Patent Application WO/2018/020537
Kind Code:
A1
Abstract:
[Problem] To provide a coupling tool in which engagement between a first coupling member and a second coupling member during rotational driving can be made more reliable. [Solution] A coupling tool 1, which couples a main body B of a cleaning device A having a drive unit to a cleaning part C, is provided with a first coupling member 2 mounted to the main body B and rotated by rotational drive force from the main body B, and a second coupling member 3 mounted to the cleaning part C and coupled to the first coupling member 2. First protrusions 6 are provided to the first coupling member 2, and second protrusions 9 are provided to the second coupling member 3. The first protrusions 6 come into contact with the second protrusions 9 in the rotational direction of the first coupling member 2, whereby the second coupling member 3 rotates integrally with the first coupling member 2. Pawls 6A are provided to the first protrusions 6, and pawls 9A that engage with the pawls 6A are provided to the second protrusions 9.
