Disclosed is a device (2) for holding a cleaning wiper (1). The holding device includes: a synthetic resin body portion (10) bifurcated to have a pair of support plates (12) to be inserted into a tube(45) of the wiper; and a handle portion (30) extending from the body portion to be held by hand. Each support plate is in an elongated plate form having a width (W1) larger than a thickness (T1). Thepaired support plates extend parallel with each other to have inner side edges (12b) facing each other and outer side edges (12a) facing in opposite directions. Protrusions (15) having convexly curved edges are integrally formed on the respective outer side edges of the support plates. The paired support plates are elastically deformable to permit tip ends thereof to approach each other.
