• (b) a main lever mounted swingably to said bracket member through said first pivot and extending along said bent rod section of said handle bar, said main lever having two side walls and at the foremost end a hollow shaft extending in parallel to said first and second pivots and perforating through said main lever transversely thereof,
• (c) a retaining member supported to said hollow shaft at said main lever and holding a terminal of said control wire, and
• (d) an auxiliary lever mounted to said bracket member through said second pivot in relation of being swingable with said main lever, said auxiliary lever having a gripping portion substantially parallel to said straight rod section at said handle bar and a pivoting portion substantially parallel to said bent rod section at said handle bar, said pivoting portion having at the head portion thereof an engaging shaft parallel to the common axis of said first and second pivots and insertable into said hollow shaft, said engaging shaft being inserted into said hollow shaft to thereby engage said main lever with said auxiliary lever in a relationship for operating each of said levers together.
