In addition, since the support shaft 10 is formed so as to be inclined so that the free end 10b rises slightly, the take-up drum 3 or the watering hose wound around the take-up drum 3 and having water remaining therein is formed on the support shaft 10. When a weight load of 14 is applied, it deforms substantially horizontally.

  Therefore, since the entire outer peripheral surface 24c of the rotating shaft 24 can always be slid over the entire inner peripheral surface 10c of the support shaft 10, the winding drum 3 can always be smoothly rotated and the rotation of the rotating shaft 24 can be performed. The occurrence of uneven wear due to uneven load during sliding can be more effectively prevented.

  Further, since the body portion 20 is spaced apart from the support shaft 10 by the space portion 25, the body portion 20 is crushed inward due to the tightening force of the watering hose 14 by the squeezing force of the watering hose 14 and the swelling of the watering hose 14 during water flow. Even if deformed, the rotating shaft 24 can always be stably supported without affecting the supporting shaft 10.

  In addition, since the handle 20 is integrally provided on the outer peripheral side of the outer flange portion 22, the amount of protrusion can be sufficiently reduced as compared with the conventional case where the handle is protruded outward from the center of the flange portion. Therefore, also in this respect, it is possible to reduce the overall width, which can further promote downsizing.

  Furthermore, since the handle 7 is provided only at the upper end of the support wall 6 and the grip 19 is disposed at a position substantially above the center of the winding drum 3 via the support arms 18, 18, the compactness is further promoted. At the same time, the overall weight balance when the grip 19 is lifted is improved, and stable carrying becomes possible.

  Also, the winding drum 3 can be attached to the support wall 6 by the water sprinkling side connector 30, and a separate member for attaching the winding drum 3 is not required. Costs can be reduced.

  Further, since the sprinkling side connector 30 is used to restrict the rotation shaft 24 from coming off the support shaft 10 by the snap ring 41, the winding drum 3 can be securely attached to the support wall 6 with a simple structure. As a result, an improvement in the efficiency of the assembling work and a strong attachment can be obtained.

  Further, the engaging grooves 39 and 40 of the water sprinkling side connector 30 engage with the protrusions 26 and 27 provided on the inner surface of the tip of the rotating shaft 24 to regulate the free rotation of the water sprinkling side connector 30. The integrity with the water sprinkling side connector 30 can be secured.

  Further, the nozzle side connector 15 can be hooked by the hooking portion 16 provided at the center of one side of the frame wall portion 9 of the support wall 6, so that the watering nozzle is prevented from being dissipated, and the storing property of the watering hose 14 is improved. I do.

  In addition, since the faucet-side connector 60 can be held by the holding projections 17 and 17 provided on the other side of the frame wall 9, the accommodation of the water supply hose 45 is improved and the portability is improved. Convenience is increased. In addition, since the faucet side connector 60 can be fitted and closed by the holding projections 17, 17, it is possible to prevent soil or mud from entering the opening of the faucet side connector 60, and the water supply hose is clogged by the mud. Can be prevented beforehand. Furthermore, since the holding projections 17, 17 are formed so as to be divided in the mold opening direction of the support 2, the undercut portion is eliminated, and the workability of forming the support 2 is improved. Along with this, cost reduction can be achieved by reducing the mold cost and the amount of resin used. In addition, the locking projections 17a, 17a can prevent the faucet-side connector 60 connected to the holding projections 17, 17 from rattling or coming off, which is convenient.

  Further, the holding member 51 inserted into the connection point of the watering hose 14 with the connector 30 can prevent the watering hose 14 from being crushed when bent, and the distal end portion 51a is formed in a folded shape, so that the connector 30 is folded. When the holding member 51 is pulled after the insertion, the tip edge 51b is hooked inside the connector 30 like a fishhook, so that accidental detachment can be reliably prevented, and a strong attachment property is obtained. can get. In particular, when it is caught on the locking claw 53 provided inside the connector 30, it can be more securely fixed.
