A plurality of first slider parts(11) is formed in an outer circumference of an external case(10). A plurality of first rail parts(12) is formed in an inner circumference of the external case. A cable protective pipe(20) is received in an internal space of the external case. A plurality of second slider parts(21) is formed in an outer circumference of the cable protective pipe. A plurality of cable receiving pipes(22) is formed in an internal space of the cable protective pipe. A coupling groove(31) is formed in both sides of a fixing plate(30). A first receiving groove(41), a first rail groove(42), and a concave groove(43) are formed in a bottom receiving member(40). The first receiving groove partly surrounds a bottom part of the external case. A second receiving groove(51), a second rail groove(52), and a guard part(55) are formed in a top receiving member(50). The guard part surrounds a side wall of the first receiving groove. |
