Claims

[Claims for Utility Model Registration] 1. A hot water outlet pipe in which a pipe body 3 is covered with a cylindrical cover 2, wherein the cylindrical cover 2 has its outer surface aligned with the outer surface of the pipe body 3 in a cross-sectional view. The plurality of proximal parts 7a are formed to include a plurality of proximal parts 7a located close to each other or in a state close thereto, and a plurality of separated parts 7b separated from the outer surface of the tube body 3 than the proximal parts 7a, and the plurality of proximal parts 7b, the tapping pipe is configured to be positioned with respect to the pipe main body 3. 2. The tapping pipe according to claim 1, wherein the cylindrical cover 2 is formed in a bellows shape including protruding portions 2a and concave groove portions 2b alternately along the longitudinal direction,
In addition, the depth of the groove-shaped portion 2b of the spaced-apart portion 7b is adjusted so that the groove-shaped portion 2b of each of the proximal portion 7a and the spaced-apart portion 7b is located close to or close to the outer surface of the tube body 3. The depth of the concave groove portion 2b of the proximal portion 7a is greater than the depth of the groove portion 2b of the proximal portion 7a. 3 The tube body 3 is covered with a cylindrical cover 2, and the cylindrical cover 2 has a protruding portion 2a and a groove portion 2b.
The cylindrical cover 2 is a tap pipe having a bellows-like shape and alternately provided along the longitudinal direction, and the cylindrical cover 2 is located close to the outer surface of the pipe main body 3 or close to the groove-shaped portion 2b in a cross-sectional view. It is formed to include a plurality of proximate portions 7a' located close to the proximate portions 7a' and a plurality of spacing portions 7b' separated from the outer surface of the tube body 3 than the proximal portions 7a', and the plurality of proximal portions 7a' Therefore, the tapping pipe is configured to be positioned with respect to the pipe main body 3.
