The present invention relates to an apparatus for adjusting an angle of an arm of a streetlight pole for a streetlight, capable of firmly fixing an arm of a streetlight pole to an upper portion of a prop through a process of simply inserting a vertical pipe of the arm of the streetlight pole to the upper portion of the prop, and easily adjusting an angle of the arm of the streetlight pole through a process of extracting only a portion of the vertical pipe of the arm of the streetlight pole at an upper side of the prop, rotating the extracted portion, and inserting the extracted portion again. The apparatus for adjusting an angle of an arm of a streetlight pole for a streetlight comprises, which includes the prop stood on the ground and having an open upper portion, a vertical connection pipe disposed on an upper portion of the prop and having an open lower portion, and a streetlight pole arm formed as an arm protruding from a lateral portion of the vertical connection pipe and having a lamp provided in an end portion thereof, comprises a fixed pipe fixed to an upper portion within the prop and having a vertical assembling hole formed in the center thereof, a connection unit formed below the vertical connection pipe and inserted into the fixed pipe 3 in the center of a lower portion thereof, and a locking unit provided within the fixed pipe such that a portion thereof protrudes upwardly and fixing the streetlight pole arm not to be rotatable by pressing the connection unit downwardly. |
