摘要： An oil tank including an oil tank body for storing oil and an oil filter disposed between an oil inlet for allowing oil into the oil tank body and an oil outlet for sending oil out. An oil inlet chamber is formed, inside the oil tank body, from a portion of the side wall, a portion of the bottom wall and the inner wall of the tank body, and communicates with the oil inlet. The oil filter has a substantially flat shape and forms a portion of the inner wall. By the use of the oil filter having a reasonably large mesh area, independently of the diameter of the oil inlet, the oil filter is protected against a mesh damage and is prevented from being detached. Since no excessively large area mesh is required, no particular rise in material costs is expected. A substantially flat surface structured oil filter is easy to fabricate and less costly to fabricate as well.
摘要翻译：一种油箱，包括用于储存油的油箱体和设置在油入口之间的用于使油进入油箱本体的油过滤器和用于输出油的出油口的油过滤器。在油箱主体内部，从侧壁的一部分，底壁的一部分和罐体的内壁形成进油室，并与油入口连通。油过滤器具有基本平坦的形状并形成内壁的一部分。通过使用具有相当大的网眼面积的油过滤器，与油入口的直径无关，可以防止油过滤器免受网损，并防止其脱离。由于不需要过大的面积网格，所以不期望材料成本的特别上升。基本平坦的表面结构油过滤器易于制造并且制造成本也较低。

摘要： A structure in which a reservoir is supported by a bracket. The bracket has a side plate facing the external circumference of the reservoir and a bottom plate facing the bottom of the reservoir. An insert fitting portion formed onto the reservoir is fitted from above into a receiver fitting portion formed onto the side plate. A lock member is supported by the side plate like a cantilever at the upper edge of an opening formed on the side plate. A catch portion formed on the reservoir forces the lock member to displace elastically so that the lock member recedes from the reservoir in the course of fitting of the insert fitting portion into the receiver fitting portion. The side plate is elastically deformable in company with the elastic displacement of the lock member. When the fitting operation is completed, the lock member comes close to the reservoir to recover its original position and is placed on the top of the catch portion to prevent the upward dismount of the reservoir out of the bracket. An auxiliary receiver fitting portion is formed onto the bottom plate, and an auxiliary insert fitting portion is formed onto the reservoir, and thus, the reservoir is supported by the bracket at two support areas.
摘要翻译：储液器由支架支撑的结构。支架具有面向储存器的外周的侧板和面向储存器底部的底板。形成在储存器上的插入装配部分从上方装配到形成在侧板上的接收器配合部分中。在侧板上形成的开口的上边缘处，锁定构件像悬臂一样由侧板支撑。形成在储存器上的卡扣部分迫使锁定件弹性移位，使得锁定件在插入装配部分嵌入接收器配件部分的过程中从储存器中退出。侧板随着锁定构件的弹性位移而弹性变形。当装配操作完成时，锁定构件靠近贮存器以恢复其原始位置并且被放置在捕获部分的顶部上，以防止储存器向上卸下支架。辅助接收装置部分形成在底板上，并且辅助插入装配部分形成在储存器上，因此储存器由支架在两个支撑区域支撑。

摘要： A flow control apparatus is disclosed which includes a housing, a cylinder disposed in the housing and a spool disposed in the cylinder while being urged in one direction along the axial direction of the cylinder. The spool slides along the axial direction against the urging force, to adjust the flow quantity of a fluid. A stopper is disposed in the housing for restricting the range of the sliding movement of the spool toward the urging direction. A pair of engaging projections are disposed on the peripheral wall of either the housing and the stopper and are separated from each other by substantially 180 degrees, and an engaging hole disposed in the other of the peripheral wall and the stopper so as to engage at least one of the engaging projections. This at least one projection is engaging with the engaging hole by the urging force acting on the spool, to attach the stopper to the housing.

摘要： In an electric power steering device, a driven gear of a deceleration gear mechanism for transmitting rotation of an electric actuator for generating auxiliary steering power has a gear body made of a synthetic resin material. At least the outer periphery of a metal core ring is covered by the gear body. The gear body is molded and integrated with the core ring by injecting synthetic resin material into a mold, in which the core ring is inserted. A plurality of teeth, each of which has faces which run in the direction of the axis of rotation of the driven gear, are formed on the outer periphery of the core ring so as to be arranged at intervals in a circumferential direction. The synthetic resin material that constitutes the gear body is filled in the spaces between the teeth of the core ring.

摘要： A gearing radius of a worm wheel is set corresponding to a neighborhood region of a steering neutral position, in such a way as to be relatively large. Thus, backlash is made to be relatively small. This prevents noises from being produced when an automobile travels straight on a bad road. Conversely, the backlash is set corresponding to most of regions of steering angles, which are within the remaining region thereof, in such a manner as to be relatively large. Thus, increase in resistance torque is suppressed. This is realized by a simple configuration in which a bias portion is provided in a part of the profile of teeth. In a case where power is transmitted from an electric motor by a worm shaft and a worm wheel during a steering operation, noises are hard to be produced even when the automobile travels on a bad road.
摘要翻译：蜗轮的齿轮半径被设定为对应于转向中立位置的邻域，以相对较大的方式。因此，齿隙相对较小。这样可以防止汽车在恶劣的道路上直线行驶时产生噪音。相反，对应于处于其剩余区域内的转向角的大部分区域，以相对较大的方式设定齿隙。因此，抑制了电阻转矩的增加。这通过简单的构造来实现，其中在牙齿轮廓的一部分中设置偏置部分。在转向操作期间通过蜗杆轴和蜗轮从电动机传递动力的情况下，即使在汽车在恶劣的道路上行驶时也难以产生噪声。

摘要： A planetary gear apparatus whose gears are all constituted by continuous shifted gears. A backlash between the input sun gear and each of the input side planetary gears is adjusted by pressing a second carrier plate supporting each integrated pair of the input side planetary gears and the output side planetary gears and moving it in the axial length direction by a ball bearing by a screwing operation of an adjusting nut. A backlash between the output sun gear and each of the output side planetary gears is also adjusted by pressing the output sun gear and moving it in the axial length direction by the ball bearing by the screwing operation of the adjusting nut. Accordingly, the backlash of all meshing portions can be adjusted during or after completion of the assemblage.
