  • Publication number: 20050271456
    Abstract: Disclosed is a cleaning device with a squirter for squirting liquid forward of a cleaning head. The cleaning head has a nozzle head with a nozzle. A liquid receiving part is provided to extend from beneath an orifice of the nozzle toward a front face of the cleaning head. Liquid dripping from the orifice of the nozzle can be led down an inclined top face of the liquid receiving part to the outside of the cleaning head, preventing the cleaning head from being soiled with a detergent, a wax or the like.

  • Publication number: 20050271457
    Abstract: Disclosed is a cleaning device with a squirter for squirting liquid forward of a cleaning head. The cleaning head has a nozzle head whose squirt surface is curved. In the nozzle head, squirt directions of nozzles, which are arranged to fan out at a squirt angle, are substantially perpendicular to tangents to the squirt surface. Therefore, liquid squirted from the nozzles tends to fly straight along the squirt directions without being drawn to the squirt surface.

  • Publication number: 20050097691
    Abstract: Disclosed is a holding device including: a telescopic handle having axially opposed front and rear ends and constructed of at least two separate shafts, of which a front-side separate shaft axially fits within a rear-side separate shaft being a hollow cylinder; and a support member provided at the front end of the telescopic handle for attachment of a cleaning wiper. The front-side separate shaft has an axially extending elastic arm and an engaging projection provided at a leading end of the elastic arm, while the rear-side separate shaft has a through-hole passing through a cylinder wall thereof, in which the engaging projection engages when the front-side separate shaft projects from the rear-side separate shaft by a predetermined length. Pressing the engaging projection, which engages in the through-hole, from outside the rear-side separate shaft permits release of the engaging projection from the through-hole.
