According to the above-mentioned conventional pipe cover, since the engaging portion is formed so as to be exposed in the pipe containing space, the pipe is arranged in the pipe containing space and each divided cover member is arranged. When engaging each other by the engaging portion, there is a risk that the pipe may come into direct contact with the engaging portion, and the pipe is made of a soft material, or a soft coating on the outer peripheral portion. In the case of a pipe having a layer (for example, an air-conditioning pipe having a heat insulating coating layer made of foamed resin), as shown in FIG. There is a problem that some of them are easily bitten, which may damage the pipe (or its coating layer). Also, in order to engage both split cover members with each other so that the pipe does not bite in the engaging part, it is necessary to pay special attention when aligning the split cover members and perform the engaging work carefully. There is also the problem of reduced efficiency.

Therefore, an object of the present invention is to solve the above problems and to provide a pipe arranged in the pipe accommodation space with a soft material or with a soft coating layer on the outer peripheral portion. However, piping (or its coating layer) on the engaging part
To provide a pipe cover that can be easily engaged without biting a part of the pipe cover.

[0005]

To achieve this object, the pipe cover according to the present invention is characterized in that it is provided between two adjacent divided cover members among a plurality of divided cover members formed in the circumferential direction. In addition, a protrusion is provided on one of the split cover members on the inner side of the cover with respect to the engaging portion that is engageable by aligning both split cover members along the radial direction. There is a place.

It is preferable that the protrusion is formed over the entire length of the divided cover member, and further,
A rib portion is preferably provided between the engaging portion and the protruding portion.

[0007]

Since the projecting portion located at the inner side of the cover of the engaging portion with a gap is provided on one of the split cover members, it is arranged in the pipe accommodating space when the adjacent split covers are engaged with each other. The protruding portion can prevent and prevent the pipe to be directly contacted with the engaging portion and biting. Therefore, even if the pipe is made of, for example, a soft material, or is provided with a soft coating layer on the outer peripheral portion, the pipe is accompanied by the engagement between the split cover members. It is possible to prevent the soft portion of the above from being bitten by the engaging portion, and it is possible to efficiently perform the work of installing the pipe cover without paying particular attention to the engaging work of the divided cover members as in the conventional case.

If the projecting portion is formed over the entire length of the split cover member, the pipe can be guarded over the entire length of the engaging portion, and the engaging portion is less likely to be bitten. it can.

Furthermore, if a rib portion is provided between the engaging portion and the protruding portion, the protruding portion can be reinforced by the rib portion, and the rib portion can be provided between the engaging portion and the protruding portion. It is possible to easily provide the protrusion in the state where the gap is formed.

[0010]

Therefore, according to the pipe cover of the present invention,
Even if the pipe arranged in the pipe accommodation space is made of a soft material or has a soft coating layer on the outer peripheral portion, a part of the pipe (or its coating layer) is provided at the engaging portion. Since it is possible to easily engage with each other without biting, it is possible to improve the assembly work efficiency of the pipe cover.
