1. A sealing structure for vehicle roof racks, comprising:
a first pipe having a male end which includes a first hole defined through a wall thereof;
a second pipe having a female end which includes a second hole defined through a wall thereof, an outer diameter of the male end of the first pipe being smaller than an inner diameter of the female end of the second pipe, the male end being inserted into the female end;
a sealing member having a first end, a second end and a shank formed between the first and second ends, the first end of the sealing member having at least one first sealing portion which seals an inner periphery of the male end, the at least one first sealing portion comprising at least one radially extending flange extending from the first end that contacts an entire circumference of the inner periphery of the male end to seal the inner periphery of the male end, the second end of the sealing member having at least one second sealing portion which seals an opening of the male end and seals an inner periphery of the female end, the at least one second sealing portion comprising at least one radially extending flange extending from the second end that abuts and covers the opening in the male end to seal the opening in the male end and contacts an entire circumference of the inner periphery of the female end to seal the inner periphery of the female end, the shank having a positioning hole defined radially therethrough, the shank including a third sealing portion formed thereto, the third sealing portion comprising at least one radially extending flange extending from the shank that contacts an entire circumference of the inner periphery of the male end adjacent the opening of the male end, the positioning hole located between the at least one first sealing portion and the third sealing portion so as to form a room between the at least one first sealing portion and the third sealing portion, and
at least one bolt extending through the first and second holes and the positioning hole to connect the male end to the female end, the at least one bolt including a head and a threaded rod which extends from the head, a distal end of the threaded rod extending through the positioning hole, wherein the positioning hole is an elongate slot that is elongated along a longitudinal axis of the sealing member and concentric with longitudinal axes of the first and second pipes, so as to facilitate alignment and provide for easier assembly of the bolt within the first and second holes and the positioning hole.
