摘要： This brush holder assembly includes: a brush holder formed in a disk shape by molding of insulating resin, and including a pair of box fixing sections each including a groove formed from an outer peripheral side toward inside: and brush box assemblies each having a brush box which houses a brush therein, each of the brush box assemblies being disposed in the box fixing section. Each of the brush box assemblies is formed of box-like metal, and has a plurality of mounting legs. Additionally, each of the box fixing sections of the brush holder has a plurality of mounting holes. In this brush holder assembly, these mounting legs are inserted into the respective mounting holes, and the brush box assembly is fixed. Furthermore, in the brush holder assembly of the present invention, the brush holder assemblies face the brush holder through gaps. Additionally, a commutator motor of the present invention includes the above brush holder assembly.

摘要： A motor according to the present invention includes bearing (11) which includes: inner ring (11a) having upper end surface (11d), outer ring (11b), and balls (11c) between inner ring (11a) and outer ring (11b). Pressurizing spring (12) is inserted onto rotary shaft (3), is located between core (4) and bearing (11), and provides bias forces in the axial direction of rotary shaft (3). Outer ring (11b) is pressed to fit into bearing holding part (9a). Inner ring (11a) is fitted onto rotary shaft (3) with gap (15) therebetween. Upper end surface (11d) of inner ring (11a) is in contact with pressurizing spring (12). Pressurizing spring (12) applies the bias forces of different strengths onto a surface in which upper end surface (11d) contacts with pressurizing spring (12), along a circumferential direction with the axial direction as a center.
摘要翻译：根据本发明的电动机包括轴承（11），其包括：在内圈（11a）和外圈（11b）之间具有上端表面（11d），外圈（11b）和滚珠（11c）的内环（11a））。加压弹簧（12）插入到旋转轴（3）上，位于芯体（4）和轴承（11）之间，并且在旋转轴（3）的轴向方向上提供偏压力。外圈（11b）被按压以装配到轴承保持部（9a）中。内环（11a）在其间具有间隙（15）安装在旋转轴（3）上。内圈（11a）的上端面（11d）与加压弹簧（12）接触。加压弹簧（12）沿轴向作为中心的周向施加不同强度的偏压力到上端面（11d）与加压弹簧（12）接触的面上。
