INSTRUCTIONS (2) The base end of a pair of terminals of fixed power, the motor fixed to the motor body, characterized by a grounding portion is provided at a free end of each of the elastic terminals, and a spacing of the grounding portions arranged at the left and right positions across a central axis of the motor casing is made larger than a diameter of the motor casing; the base end of each terminal is Fixed to the rear end of the motor body. As a result of using the elastic terminal, the motor is intended to be mounted on a mobile phone or the like, thereby avoiding the need for welding and improving the assembly work efficiency of the machine. The grounding portions of the pair of terminals are arranged with the center axis of the casing interposed therebetween, and the interval between the land portions is made larger than the diameter of the casing, so that the stability of the motor support when the motor is mounted can be improved. Further, the amount of elastic deformation (stroke amount) of the terminal when the motor is mounted can be increased while avoiding the influence of the outer shape of the casing as much as possible. In this way, the terminal fully utilizes the elastic force required to push the device to the electrical contact, making the electrical connection a true one. Further, as described above, the interval between the land portions is considered to give a sufficient stroke at the terminal, and at the time of elastic deformation, the influence of the motor casing is avoided as much as possible, and therefore, the elastic deformation of the terminal can be performed when the motor is mounted. The height of the rear motor is as close as possible to the outer dimensions of the casing. As a result, the installation of a motor having a small height and a small size contributes to the thinning of a mobile phone or the like. Further, each of the terminals has a base end portion that is fixed to the motor body, and an elastic portion that extends from the base end portion and that has a ground portion provided at the free end. It is preferable that the elastic portion is disposed on one side of the motor case. As a result of the elastic portion on one side of the motor casing, the elastic portion is not required to be in contact with the motor casing, and the elastic portion can be sufficiently elastically deformed. Therefore, the size of the paper with a small installation height can be achieved. The Chinese National Standard (CNS) A4 specification (210X297 mm) is applicable.

INSTRUCTIONS (3) Motivation to promote thinning on the machine side. (Please read the precautions on the back side and fill out this page.) Further, the elastic portion has a first portion that extends along the axis of the output shaft and a second portion that extends rearward from the front end of the first portion via the bent portion. . Thereby, an appropriate elastic force can be generated in the elastic portion. Further, the base end portion extends toward the output shaft in the vertical direction and bulges toward one side of the motor casing; the elastic portion is from the base end portion along the axis of the output shaft. The shape extension is ideal. When the terminal has an elastic portion extending approximately u-shaped along the axis of the output shaft, the mounting height dimension of the motor tends to become large, so that the elastic portion can be disposed on one side while avoiding the motor casing, and has a larger effect. Also, it is preferable to have an eccentric fixed weight on the output shaft. With such a configuration, a vibration motor can be constructed, and particularly in a vibration motor, the support stability of the motor is important. Further, it is preferable to cover the motor case by a rubber holder. When the motor is vibrated by the weight, unnecessary vibration sounds from the frame of the machine (such as a mobile phone) do not occur. Printed by the Ministry of Economic Affairs, the Intellectual Property Bureau, and the Consumer Cooperatives. The motor of the present invention is highly versatile and can be applied to various vibration alarms. For example, as an example of a vibration alarm, there is a game machine such as a mobile phone, a caller, or a PDA that carries an information terminal device or a controller of an entertainment device. 4.

A curved portion 13a is formed, and a gold-plated ground portion 14 is formed on the surface of the bent portion 13a, and the ground portion 14 is electrically connected to the predetermined electrical contact 7a of the circuit board 7. Indeed. The elastic portion is extended from the expansion portion 19 in a cantilever support state, and the elastic portion 30 can be positioned on one side of the motor casing 2. Each terminal 8 is housed in a slit 17a (see FIG. 3) integrally formed in the leg portion 17 of the bracket 5 at the rear end of the motor case 2, and the third portion is exposed from the slit 17a. 1 3. As a result, the entire terminal 8 which is easily damaged during the handling operation is not exposed, and the portion required for electrical bonding can be easily seen, and the workability for assembly to the machine can be improved. Further, the ground portion 14 of the terminal 8 is close to the rear end of the motor case 2, and as a result, the balance of the motor 1 on the circuit board 7 can be made good. Further, by using the terminal 8 formed by bending, the terminal can be formed with a simple structure and at a low cost, and as a result, the manufacturing cost can be reduced. Further, as shown in Fig. 4, the ground portion 14 is arranged at a bilaterally symmetrical position across the central axis P of the motor casing 2, and the expansion portion 30 is used at the terminal 8 to set the interval L of the ground portion 14'14. Make it bigger than the motor case 2 (please read the back of the note first and then fill out this page) This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) -10- 1316779 A7 B7 Ministry of Economic Affairs Intellectual Property Bureau 8 Workers' consumption cooperatives printed five, invention description (7) diameter R. As a result, when the motor 1 is mounted on the circuit board 7, the support stability of the motor 1 can be improved. In particular, in the vibration motor having the weight 6, the support stability of the motor 1 is extremely important. Further, as a result of making the interval L between the ground portions 14 and 14 larger than the diameter R of the motor case 2, the amount of elastic deformation of the elastic portion 30 when the motor is mounted can be increased while avoiding the influence of the outer shape of the motor case 2 ( Stroke amount). As a result, when the terminal 8 is pressed against the electrical contact 7a of the mobile phone or the like, a sufficient elastic force can be generated in the elastic portion of the terminal 8, and the electrical connection to the electrical contact 7a can be electrically connected. Further, as described above, the interval L between the ground portions 14 and 14 is considered to minimize the influence of the motor case 2 during elastic deformation in a state where the elastic portion 30 of the terminal 8 is provided with a sufficient stroke. When the motor is mounted, the mounting height dimension Η (see Fig. 1) of the motor 1 after the elastic deformation of the elastic portion 30 is as close as possible to the outer diameter dimension R of the motor case 2. As a result, the motor 1 having a small mounting height Η is realized, thereby promoting the thinning of the mobile phone as an example of the object to be mounted. Further, as the elastic portion 30 is positioned on one side of the motor case, and the interval between the elastic portions 30, 30 arranged is larger than the diameter of the motor case 2, the elastic portion 30 does not have to be in contact with the motor case 2, The elastic portion 30 can be sufficiently elastically deformed. In particular, in the motor 1 in which the terminal portion 8 having the elastic portion 30 extending approximately U-shaped along the axis of the output shaft 3 is used, the height dimension of the mounting height tends to be high, which is effective. Further, the motor case 2 of the motor main body is covered by a rubber holder 16 as shown in Figs. 7 to 11 . Therefore, the motor 1 (Read the first note on the back and fill in the page) The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -11 - 1316779 A7 B7 V. Invention description (8 When the vibration is performed by the weight 6, the unnecessary vibration sound does not occur in the casing of the machine (for example, a mobile phone). The motor of the present invention is not limited to the above, and for example, the motor 40 shown in Fig. 12 has another terminal 41. The terminal 41 is formed by a bending process of a thin elastic plate cut into a predetermined shape. The terminal 41 has a base end portion 42 fixed to the motor body A, and an elastic portion 43 extending from the base end portion 42 and having an elastic force in a direction orthogonal to the output shaft 3. Each of the elastic portions 43 located on both sides of the motor casing 2 has a first portion 44 extending along the axis of the rotary shaft 3. Further, the elastic portion 43 is a second portion 45 having a bent portion B in which the front end of the first portion 44 is folded in a U or V shape approximately parallel to the first portion 44. The second portion 45 is of approximately the same length as the first portion 44. Further, the third portion 46 projecting outward from the rear end of the second portion 45 protrudes rearward than the rear end 47 of the motor body A. A bent portion 46a is formed at the free end portion of the third portion 46, and a land portion 49 on which the surface is gold-plated is formed by bulging at the top of the bent portion 46a.
