  The hand guide roller is provided with small rolling rollers before and after the main frame, and is used for initial rolling of asphalt pavement and compacting of relatively narrow road surfaces and sites. This hand guide roller has a base frame installed on the main frame on which a rolling roller and a vibration generator are mounted via a vibration isolating material such as an anti-vibration rubber. It is configured with an oil tank. This hand guide roller grips the handle attached to the base frame by the operator and operates the operation lever and switch attached to the end of the handle to start and stop the engine, forward rotation of the rolling roller, Reverse rotation operation and drive / stop switching operation of the vibration generator are performed. The water stored in the water tank mounted on the base frame is sprinkled on the pressure roller to form a water layer on the surface of the pressure roller, so that the paving material such as asphalt adheres to the pressure roller. To prevent that.

  As described in Patent Document 1, the water spray device for the hand guide roller includes the water tank, a water spray pipe attached along the axial direction of the pressure roller, corresponding to the front and rear pressure rollers, and the water spray. A hose provided between the pipe and the outlet pipe of the water tank. The watering pipe has a plurality of small holes through which water flows out. When the valve at the outlet of the water tank is opened, the non-pressurized water in the water tank flows through the hose to the sprinkling pipe by natural flow, and further flows down from the small hole of the sprinkling pipe onto the pressure roller.

  In the conventional watering apparatus, the connection port with the hose provided in the watering pipe is provided with a structure protruding so as to be perpendicular to the watering pipe. The connection port has a cylindrical shape, and a plurality of tapered annular protrusions are formed on the outer periphery of the cylindrical connection port so that the hose does not easily come out of the connection port. Then, the hose is externally fitted by pressing the end of the hose against the connection port provided with the annular protrusion, and the hose is connected to the watering pipe.
