PROBLEM TO BE SOLVED: To provide a bolting fastener easy to manufacture while avoiding the disadvantages of a known device. SOLUTION: The bolting fastener 1 joins a first angle piece 3 to a second angle piece 4 of a brush unit 2. The first angle piece 3 is arranged on a supporting component of a head piece of an escalator or of a head piece of a moving walkway. An adapter arranged between the angle pieces 3, 4 allows an accurate two-dimensional position change of the brush unit 2 to the first angle piece 3 or its original position without an auxiliary means. A bolt 6 with a nut 7 and a washer 7.1 are used for integrally holding the two angle pieces 3, 4 and the adapter 5. COPYRIGHT: (C)2006,JPO&NCIPI
