摘要： A seal member of a seal unit of a valve timing adjusting device has foot portions and protrusive guides protruding from a seal reverse plane along internal surfaces of the foot portions. A plate spring of the seal unit has foot portions and fork portions arranged on top ends of the foot portions. A slit is formed in each fork portion to allow the insertion of the protrusive guide when the plate spring is fitted to the seal member. The positional relationship between the slit and the protrusive guide is determined on condition that the plate spring fitted to the seal member does not detach from the seal member and the plate spring does not collide with the protrusive guide when the plate spring is bent to arrange the seal unit in the valve timing adjusting device. When the plate spring is fitted to the seal member, the slits of the fork portions are positioned just above the protrusive guides, and the plate spring is dropped according to the gravitational force. Thereafter, stopper portions are formed by deforming top end portions of the protrusive guides according to ultrasonic wave machining method, and the plate spring is prevented from detaching from the seal member.
摘要翻译：气门正时调节装置的密封单元的密封构件具有从脚部的内表面从密封反向平面突出的脚部和凸出引导件。密封单元的板簧具有布置在脚部的顶端上的脚部和叉部。在每个叉部形成狭缝，以允许当板簧装配到密封构件时插入突出引导件。狭缝与突出引导件之间的位置关系是在安装到密封件上的板簧不从密封件脱离的情况下确定的，并且当板簧被弯曲以布置弹簧时，板簧不会与突出引导件碰撞气门正时调整装置中的密封单元。当板簧装配到密封构件上时，叉部的狭缝位于突出导向件的正上方，并且板簧根据重力下落。此后，通过根据超声波加工方法使凸出引导件的顶端部变形来形成止动部，并且防止板簧从密封部件脱离。

摘要： A roller body receives a tape at a cylindrical surface. First and second flange members are located adjacent one and the other ends of the roller body for movement in the axial direction of the roller body, respectively. If one edge of the tape creases, the movement of the first flange member is restrained, so that a reference position can be set for the other edge of the tape in the first flange member. If the other edge of the tape creases, the movement of the second flange member is restrained, so that a reference position can be set for the one edge of the tape in the second flange member. In either case, the centerline can be prevented from shifting. Employment of the guide roller of this type in a tape drive allows a head to reliably follow a servo track on the tape.
摘要翻译：辊体在圆柱形表面接收带。第一和第二凸缘构件分别邻近辊主体的一端和另一端定位，以分别沿着辊体的轴向运动。如果胶带的一个边缘折皱，则第一凸缘部件的移动被抑制，使得可以为第一凸缘部件中的带的另一个边缘设置基准位置。如果胶带的另一边缘折皱，则第二凸缘部件的移动被限制，使得可以为第二凸缘部件中的带的一个边缘设置基准位置。在任一种情况下，可以防止中心线偏移。使用这种类型的导向辊在磁带驱动器中允许磁头可靠地跟随磁带上的伺服磁道。
