    • Construction is achieved that is capable of maintaining overall strength of a cylindrical-shaped steering column, while at the same time making it possible to make the thickness part of the steering column thin. An outer column 10b, which is a column member of a steering column is formed by connecting in the axial direction a main portion 18 made using a light metal alloy with a cylindrical member 19 made of an iron-based alloy by a concave groove 20 that is formed around the outer circumferential surface of the front end section of the cylindrical member 19 engaging with a protrusion 21 that is formed around the inner circumferential surface of the rear end section of the main portion 18. A ring 22 made using a metallic material is fitted and fastened inside the inner diameter side of the cylindrical member 19 in the connecting section between the main portion 18 and the cylindrical member 19.

    • Construction is achieved wherein the rear section of a steering column 6a can be prevented from displacing upward regardless of the occurrence of a secondary collision, and thus can effectively protect the driver. Capsules 28 are supported by a bracket on the vehicle body side. An installation plate section 14b of a bracket 13 on the housing side is held between a top plate section 29 and bottom plate section 30 of each of the capsules 28 so that the installation plate section 14b can displace in the forward direction during a secondary collision. The top and bottom plate sections 29, 30 extend forward to a position where they can support the installation plate section 14b even when the bracket 13 on the housing side has displaced in the forward direction due to a secondary collision. Alternatively, a suspended arm that functions in the same way is provided on the bracket on the vehicle body side.
    • 实现了可以防止转向柱6a的后部向上移动而不考虑二次碰撞的结构,从而可以有效地保护驾驶员。 胶囊28由车体侧的支架支撑。 在壳体侧的支架13的安装板部分14b被保持在每个胶囊28的顶板部分29和底板部分30之间,使得安装板部分14b可以在二次碰撞期间沿向前方向移位。 即使当壳体侧的支架13由于二次碰撞而向前方移位时,顶板部分29和底板部分30向前延伸到可以支撑安装板部分14b的位置。 或者,在车身侧的支架上设置以相同方式起作用的悬臂。

    • A mobile terminal includes a battery; a power supply block which supplies power of the battery; and a radio communication block which communicates with a base station when the power is supplied from the battery through the power supply block. The mobile terminal further includes a first switch which is interposed between the power supply block and the radio communication block; and a key operation section to which the power is always supplied from the battery through the power supply block. A control unit controls the first switch to stop the power supply from the battery to the radio communication block in response to a manual operation of the key operation section.

    • Construction is achieved wherein a steering wheel can displace smoothly in the forward direction during a secondary collision, even when an electric motor 13a of an electric power steering apparatus protrudes to the side. The distances from the center axis of the steering column 6c to the connecting sections between the installation plate sections 17e, 17f and a portion 34 fastened to the vehicle body are different from each other on both sides of the steering column 6c, such that the distance Le for the installation plate section 17e located on the side where the electric motor 13a is located is shorter than the distance Lf for the installation plate section 17f that is located on the opposite side from the electric motor 13a. The ratio of a separation load that is applied to the installation plate section 17e on the side where the electric motor 13a is located is made to be large. The tendency for the dropping away toward the front on the side where the electric motor 13, having a large inertial mass, is located, being difficult, is cancelled out by the ease of the dropping away of the installation plate section 17e.
    • 实现了即使在电动助力转向装置的电动机13a向侧方突出的情况下,二次碰撞期间方向盘可以向前方向平滑地移动的结构。 转向柱6c的中心轴线与安装板部分17e,17f之间的连接部分和固定在车身上的部分34之间的距离在转向柱6c的两侧彼此不同,使得距离 位于电动机13a所在一侧的安装板部分17e的距离Le比位于与电动机13a相反一侧的安装板部分17f的距离Lf短。 在电动机13a所在的一侧施加到安装板部17e的分离负荷的比例大。 由于安装板部分17e容易脱落,因此难以将惯性质量较大的电动机13向前方向前方倾斜的倾向消除。
