摘要： A direct current motor includes a stator generating a magnetic field therein and a rotor having an armature and rotating inside the stator. A commutator for supplying electric current to the armature is connected to the rotor. The commutator is composed of plural commutator segments bonded together with an insulating resin material. Each commutator segment includes an anchor portion formed at a radial inside and a projecting portion extending in an axial direction, and both portions are embedded in the insulating resin. The commutator segments are firmly bonded with the insulating resin, and the bonding strength is increased without enlarging the commutator size.

摘要： In an electromagnetic switch of a starter, a bobbin has two terminal holders on a flange. Each of the terminal holders defines a slot on its end surface and a terminal is press-fitted in the slot in an axial direction of the bobbin. An end of an excitation coil wound around the bobbin is pulled out the bobbin and connected to the terminal. A molded cover provides a through hole and is mounted on the terminal so that the terminal passes through the through hole. A sealing member is press-fitted on the terminal to air-tightly seal the through hole. A rod cover fitted on a rod supporting a movable contact has slits on its cylindrical part in the axial direction. The slits are closed before a distal end of the cylindrical part.

摘要： An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.

摘要： An electromagnetic switch for a starter is provided. In the switch, a switch case has an open end formed and a molding cap has two terminals connected electrically to external leads and a fitting end. The fitting end is mutually fitted to the open end of the switch case. A pair of fixed contacts is disposed inside the molding cap, each fixed contact being integrally secured to each terminal. A movable contact is movably disposed to face the pair of fixed contacts. An excitation coil generates a magnetic force necessary for driving the movable contact. Further, the switch case includes a winding-up belt piece integrally formed to a circumference of the open end to extend outwardly in its axial direction. The molding cap includes a circumferential groove formed on an outer surface of the fitting end of the molding cap, the winding-up belt piece winding up the whole circumferential groove.

摘要： In a starter, a pinion is fitted on a pinion shaft such that a rear end surface of the pinion is pressed against a thrust receiving wall provided on the pinion shaft, while a front end surface of the pinion is pressed backward by a detent ring. The detent ring has a tapered surface and fitted in a recess provided on a pinion shaft. A front rising wall defining the recess has a tapered wall so as to correspond to the tapered surface. Since resiliency of the detent ring constricting radially inward is applied to the tapered wall, a component force of the resiliency pressing the pinion axially backward is generated. Thus, the pinion is restricted from moving axially backward by pressing a rear end surface against a thrust receiving wall of the pinion shaft, while the front side surface of the pinion is pressed axially backward through the detent ring.

摘要翻译： 在起动器中，小齿轮安装在小齿轮轴上，使得小齿轮的后端表面被压靠在设置在小齿轮轴上的推力接收壁上，同时小齿轮的前端表面通过制动环向后推。 制动环具有锥形表面并且装配在设置在小齿轮轴上的凹部中。 限定凹部的前上升壁具有与锥形表面对应的锥形壁。 由于向锥形壁施加限制环的径向向内收缩的弹性，所以产生沿轴向向后推动小齿轮的弹力的分力。 因此，通过将后端面压靠在小齿轮轴的推力接收壁上，小齿轮的前侧面通过制动环被轴向向后推压而限制小齿轮的轴向移动。
