摘要： A brushless motor includes a circuit protecting case, a holder disposed on the case, a motor shaft rotatably held by the holder, a stator disposed about the holder, a yoke fixed to the motor shaft to rotate therewith, permanent magnets held by the yoke, and a circuit substrate held in the circuit protecting case. The stator includes a plurality of coils which surround the motor shaft. The circuit substrate contains a drive circuit and a control section. The drive circuit includes a switching section which switches the current path directed to the coils of the stator. A partition wall, provided in the circuit protection case, partitions the interior of the case into a first chamber and a second chamber.

摘要： In a rack guide disposed in a casing of a rack and pinion type steering system for slidably supporting a rack bar having rack teeth which engage with a pinion rotatably supported in the casing, the area for bearing the load of the rack bar can be fixed. A slide bearing member 21 has a three-layered structure consisting of a backing metal 22 made of bronze, a sintered alloy layer 23 and a synthetic resin layer 24, the surface of the synthetic resin layer 24 comprising sliding-contact surface portions 25, 26 formed intermittently with the center thereof at the center of curvature “O” of a circular outer peripheral surface of a rack bar 16 and with a radius of curvature equal to the radius of curvature R0 of the same, and the remaining surface portions 27 to 29 formed in other positions than the sliding-contact surface portions 25, 26 so as to be more dented than the sliding-contact surface portions 25, 26.
