摘要： A vibration actuator includes: a movable part including a coil or a magnet; a fixing part including the other one of the coil or the magnet; and an elastic supporting part supporting the movable part such that the movable part is movable to the fixing part. The movable part reciprocates with respect to the fixing part in a vibrating direction by interaction between the coil and the magnet. The magnet is disposed to be radially inwardly spaced apart from the coil. The elastic supporting part is fixed at its one end to the fixing part and at its other end to the movable part. The elastic supporting part has a structure for cantilevering the movable part. The coil in a state of being fixed to a resin coil holder is integrated in the movable part or the fixing part.

摘要： A vibration actuator includes: a fixing part including one of a coil and a magnet; a movable part including the other one of the coil and the magnet; and an elastic supporting part configured to support the movable part movably with respect to the fixing part. The movable part is configured to reciprocate with respect to the fixing part in a vibration direction through cooperation between the powered coil and the magnet. The magnet is disposed away from and radially inside the coil. The elastic supporting part has a plate-like shape in which one end of the elastic supporting part is fixed to the fixing part at the side of the movable part and the other end is fixed to the movable part, and cantilevers the movable part in such a manner that the movable part can reciprocate in the vibration direction.

摘要： In a motor case 1, recesses 8 are formed in inner surfaces of upper and bottom surface portions 2 and 3 (which are spaced from each other by a distance smaller than the distance between left and right side surface portions 4 and 5), thus reducing the thickness of these surface portions 2 and 3, thereby increasing a space for receiving a stator coil 10 as much as possible. Unlike a construction in which a stator coil is exposed through openings formed in a motor case, the stator coil is covered with the motor case, and therefore the motor is excellent in shielding performance and impact resistance. The motor case 1 has a square tubular shape, and can be formed by blanking, press-forging (for the purpose of forming the recesses) and bending a metal sheet, and the motor case can be produced at a low cost.
摘要翻译：在电动机壳体1中，凹部8形成在上表面部分2和下表面部分3的内表面上（它们彼此间隔开距离小于左右侧表面部分4和5之间的距离），从而减少这些表面部分2和3的厚度，从而尽可能地增加了用于接收定子线圈10的空间。与定子线圈通过形成在电动机壳体中的开口露出的构造不同，定子线圈被电动机壳体覆盖，因此电动机的屏蔽性能和耐冲击性优异。电动机壳体1具有方形管状，并且可以通过冲裁，压锻（为了形成凹部的目的）和弯曲金属板而形成，并且可以以低成本制造电动机壳体。

摘要： A magnetization pattern of a rotor magnet for a stepping motor includes a plurality of magnetization portions, which is provided on the rotor magnet in a rotation direction of the rotor magnet. The magnetization portions have different magnetic poles which are alternately arranged. Some magnetization portions of the magnetization portions have respectively magnetization widths A. Said some magnetization portions are opposed each other with a rotary axis or the rotor magnet as a center among said some magnetization portions. The other magnetization portions of the magnetization portions have respectively uniform widths B. Each of the magnetization widths A is greater than that of the uniform widths B.
