PROBLEM TO BE SOLVED: To provide a hydraulic travel motor with a reduction gear capable of recycling a carrier by using a hexagon socket head bolt or a rimmed plug instead of caulking as the means to prevent a stopper pin from coming out.SOLUTION: Planetary gear reduction mechanisms 48 and 49 disposed in a reduction gear 14 divide a planetary gear group 43 including a plurality of first planetary gears 58 and second planetary gears 59 into two stages in a speed reducer chamber 51 while a first pin member 91 and a second pin member 92 are inserted into the first planetary gears 58 and each second planetary gear 59 together with a first carrier 53 and a second carrier 54, and a bolt 96 is screwed into a hole 95 into which the pin members 91 and 92 are fitted, so that head members of the pin members 91 and 92 are pushed so as to prevent the pin members 91 and 92 from escaping from the carriers 53 and 54.SELECTED DRAWING: Figure 1 |
