がある。In each of the above-mentioned conventional protective covers, a pair of semi-cylindrical bodies are joined to form a cylindrical shape, but the joining structure of the pair of semi-cylindrical bodies is different. There is. Since the protective cover disclosed in Japanese Utility Model Publication No. 6-259 is supposed to be originally separable, there is a possibility that the joint portion may come off when an external force is applied to the protective cover from the inside to the outside. Similarly, the fairness 5-2
Also in the protective cover described in Japanese Patent No. 5305, there is a possibility that the joint portion may come off when an external force is applied from the inside to the outside.

困難であり、コストアップとなる。On the other hand, as in the cylinder assembly described in JP-A-4-215524, if the outer cylinder is fitted to the pair of inner cylinders to form a double cylinder, the joint portion of the inner cylinder will come off. However, the number of parts becomes three, and the number of materials and assembling steps increase, resulting in cost increase. In addition, although a structure for welding the joint end faces of a pair of semi-cylindrical bodies is also known (not shown), it requires a welding device, and the assembly method described above, such as misalignment during welding and burrs In comparison with the above, joining is difficult and the cost increases.
