Japanese Patent JP2020014290
Kind Code:
A
Abstract:
To securely protect a cable or the like housed inside.SOLUTION: In a cable protection conduit 4C, in a certain range continuous from a rotation center P1 located between a first reduced-diameter tube 51 and a second enlarged-diameter tube 42 in the direction of an axis J21 in the first reduced-diameter tube 51, and a certain range continuous from the rotation center P1 in the direction of the axis J21 in the second enlarged-diameter tube 42, at any position in these ranges, an inner diameter d at the position is a value obtained by the following formula (1). D*(sinθ*tanθ*cosθ)+2*x*tanθ ... (1). Here, D is the outer diameter of a cable protection tube 5A, θ is the maximum bending angle between the cable protection tube 5A and a cable protection tube joint 21, and x is the distance in the direction of the axis J21 from the rotation center P1 to the position.SELECTED DRAWING: Figure 12
