摘要： PROBLEM TO BE SOLVED: To quickly disengage a pinion from a ring gear after ignition of an engine by securing smooth movement of an SL1 plunger 36 and an SL2 plunger 47, and to suppress occurrence of arc when a main contact is closed.SOLUTION: A partition member 76 for partitioning a first movable space in which an SL1 plunger 36 can move on an inner periphery of an SL1 coil 35 in an axial direction from a second movable space in which an SL2 plunger 47 can move on an inner periphery of an SL2 coil 46 in an axial direction is arranged between the SL1 plunger 36 and the SL2 plunger 47, and a vent 77 for allowing the first movable space to communicate with the second movable space is opened on a partition bottom part 76a of the partition member 76. Since pressure variation of the first movable space and the second movable space is suppressed when the SL1 plunger 36 and the SL2 plunger 47 are moved, smooth movement of the SL1 plunger 36 and the SL2 plunger 47 can be achieved.
摘要翻译：要解决的问题：通过确保SL1柱塞36和SL2柱塞47的平稳运动，通过确保发动机点火后，使齿轮与齿圈快速脱离，并且在主接触闭合时抑制电弧的发生。解决方案：A 分隔构件76，用于分隔第一可移动空间，其中SL1柱塞36可以从SL2柱塞47可以在SL2的内周上移动的第二可移动空间沿轴向方向在SL1线圈35的内周上移动在SL1柱塞36和SL2柱塞47之间配置有螺旋弹簧46，在分隔构件76的分隔底部76a上开设用于使第一可动空间与第二可动空间连通的通气口77。由于当SL1柱塞36和SL2柱塞47移动时第一可动空间和第二可移动空间的压力变化被抑制，所以可以实现SL1柱塞36和SL2柱塞47的平滑运动。

摘要： PROBLEM TO BE SOLVED: To provide a technique for improving mountability of a starter in which an electromagnetic switch of tandem solenoid type is disposed coaxially with a pinion shaft, by shortening the whole length of an electromagnetic switch in the starter.SOLUTION: An SL1 plunger 34 is configured in such a manner that a difference is disposed on the outer circumferential surface thereof and the outer diameter of a plunger rear part 34b that is located on the rear end side from the difference is formed smaller than the outer diameter of a plunger sliding part 34a that is located on the front end side from the difference. An SL2 plunger 41 is configured in such a manner that an inner diameter of a plunger sliding part 41a of which the front end side is opened is formed larger than the outer diameter of the plunger rear part 34b. When both of the SL1 coil 28 and SL2 coil 29 are non-excited, that is, both of the SL1 plunger 34 and SL2 plunger 41 rest on the return position, the SL1 plunger 34 and the SL2 plunger 41 overlap with each other such that the plunger rear part 34b enters the inner circumference of the SL2 plunger 41.

摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine which improves the durability by prolonging the service life of a brush.
SOLUTION: In a motor 2 (the rotary electric machine) which is used in a starter 1, for example, the brush 8 is urged toward the outer circumferential surface of a commutator 7 by means of a brush spring 9. When the starter 1 is operated, the brush 8 is worn out by the sliding friction with the commutator 7. Since the worn-out part is pushed out from a brush holder 10 at any time by means of the brush 8, the brush 8 always comes into proper contact with the commutator 7. At a moment in time when the joint 12c of a lead wire 12 comes into contact with the slit end 10d, the brush is not pushed out any more and reaches the end of service life. When the lead wire 12 connected to the brush 8 is a stranded wire having a circular cross-section, the length M between the joint 12c and the slit end 10d is increased and thereby a large wear allowance of the brush 8 is taken.

摘要翻译：要解决的问题：提供一种通过延长刷子的使用寿命来提高耐久性的旋转电机。解决方案：在起动机1中使用的电动机2（旋转电机）中，例如通过电刷弹簧9将电刷8朝向换向器7的外周面侧推压。当启动器1被操作，电刷8被与换向器7的滑动摩擦磨损。由于磨损部分通过刷子8随时被从电刷架10推出，所以电刷8总是进入与换向器7正确接触。在引线12的接头12c与狭缝端部10d接触的时刻，刷子不再被推出并达到使用寿命的终点。当连接到电刷8的引线12是具有圆形横截面的绞合线时，接头12c和狭缝端10d之间的长度M增加，从而获得了刷8的大的磨损余量。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a starter equipped with an impact absorbing device maintaining stable slip torque and allowing a long operating life.
SOLUTION: A rotary disc 50 used in the impact absorbing device is formed on the whole circumference of an inner periphery of a ring shape with a plurality of teeth forming an internal gear 26 and a planetary gear of reduction gears is engaged with these teeth. The rotary disc 50 is provided integrally with the internal gear 26 of the reduction gears. In the rotary disc 50, a soft nitrocarburizing treatment is performed on the raw material of low carbon steel material or medium carbon steel material and a compound layer A of nitriding iron is formed on a surface layer part contacting with a fixed disc 49. This improves the wear resistance and the lubricating ability, and the fixed disc 49 is inhibited from wearing while ensuring the surface hardness required for the internal gear 26. The compound layer, because of having a small friction coefficient and being stable, inhibits fluctuations of the slip torque and maintains the stable slip torque.

摘要： PROBLEM TO BE SOLVED: To provide a starter capable of maintaining clutch performance for a long period of time by preventing other grease from being mixed with grease used in the clutch 4. SOLUTION: An inner space A formed inside of an inner tube 2 and an air hole 40 communicating with an outside of an outer wall part 42 are formed on an outer wall part 42 of an clutch outer 20. Also, a ring shape collar 41 cutting off connection between the inner space A and a cam chamber of the clutch 4 is provided between the inner tube 2 and the outer wall part 42 facing in an axial direction, Consequently, air compressed in the inner space A can be released to the outside of the outer wall part 42 from the air hole 40 when a pinion shaft 5 returns. As a result, since grease or the like used in a spline part can be prevented from entering the cam chamber of the clutch 4, drop of friction coefficient of the grease used in the clutch 4 can be inhibited and slip of the clutch 4 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a rotating force transmission device capable of stably absorbing excessive rotating force while suppressing an increase in rotating force which produces sliding even when oil such as lubricating oil having a low friction coefficient and high permeability enters. SOLUTION: A starter 1 has a clutch gear 4 and a barrel 5. On the inner peripheral face of the clutch gear 4, a solid lubricating layer 4c is formed which consists of a chemical coating 4a and molybdenum disulfide 4b. Onto the outer peripheral face of the barrel 5, fat 5a is applied which is formed by mixing oil having a higher friction coefficient than lubricating oil applied to a tooth portion of the clutch gear 4 and molybdenum disulfide. Then, the clutch gear 4 is shrink-fitted to the barrel 5. Even when oil such as lubricating oil having a low friction coefficient and high permeability enters between the clutch gear 4 and the barrel 5, an increase in rotating force which produces sliding is suppressed and excessive rotating force is stably absorbed.
