図１(ａ)および(ｂ)は本発明の実施例を示す振動モータ取付け部材の展開図および成形後の形状を示す図である。振動モータ取付け部材１１は金属の薄板でできており、展開図のように打ち抜き加工を施した後、Ｕ字型になるよう曲げ加工を施したものである。これをまず、円筒形振動モータ２１に溶接固定する。このとき図２(ａ)および(ｂ)に示すように振動モータ取付け部材１１と円筒形振動モータ２１の寸法関係は以下のとおりである。（１）振動モータ取付け部材１１のＵ字部の深さＤが円筒形振動モータ２１の胴部の半径d/2よりも大きい。かつ（２）振動モータ取付け部材１１のＵ字開口部Ｗが円筒形振動モータ２１の胴部の直径ｄと振動モータ取付け部材１１の板厚ｔの２倍の合計よりも大きい。かつ（３）振動モータ取付け部材１１のＵ字開口部Ｗがそれらを固定搭載する剛体のケース２２の枠幅Ｗｃよりも若干大きい。このようにして振動モータ２１を剛体のケース２２に固定搭載すると、振動モータ取付け部材１１のＵ字開口部がケース２２の枠にあたり弾性変形が起こる。そのときの力の関係は図２(ｂ)のようになり、振動モータ取付け部材１１のばね力２４の水平方向成分２５とケース２２からの反力２８がつりあい、またばね力２４の垂直方向成分２６が振動モータ取付け部材１１とケース２２の間の摩擦力２７とつりあうことによって、振動モータ２１をケース２２内に確実に組み付けることができる。このとき、振動モータ取り付け部材２１は金属の薄板から成るため厚さ０。１ｍｍとすることが充分可能であり、図３で示すゴム製の取付け部材３１よりも固定搭載に必要な体積が少なくてすむし、図４で示すＭ字型の取付け部材４１に較べてへり部分が無いために同じく固定搭載に必要な体積が少なくてすむ。[0013]
FIGS. 1A and 1B are a developed view of a vibration motor mounting member showing an embodiment of the present invention and a view showing a shape after molding. The vibration motor mounting member 11 is made of a thin metal plate, and after being punched as shown in the development view, it is bent to be U-shaped. First, this is welded and fixed to the cylindrical vibration motor 21. At this time, as shown in FIGS. 2A and 2B, the dimensional relationship between the vibration motor mounting member 11 and the cylindrical vibration motor 21 is as follows. (1) The depth D of the U-shaped portion of the vibration motor mounting member 11 is larger than the radius d / 2 of the body of the cylindrical vibration motor 21. (2) The U-shaped opening W of the vibration motor attachment member 11 is larger than the sum of the diameter d of the body of the cylindrical vibration motor 21 and twice the plate thickness t of the vibration motor attachment member 11. (3) The U-shaped opening W of the vibration motor mounting member 11 is slightly larger than the frame width Wc of the rigid case 22 on which they are fixedly mounted. When the vibration motor 21 is fixedly mounted on the rigid case 22 in this manner, the U-shaped opening of the vibration motor attachment member 11 hits the frame of the case 22 to cause elastic deformation. The relationship of the force at that time is as shown in FIG. 2B, and the horizontal component 25 of the spring force 24 of the vibration motor mounting member 11 and the reaction force 28 from the case 22 are balanced, and the vertical component of the spring force 24 The vibration motor 21 can be reliably assembled in the case 22 by balancing the friction force 27 between the vibration motor attachment member 11 and the case 22. At this time, since the vibration motor attachment member 21 is made of a thin metal plate, the thickness can be sufficiently set to 0.1 mm, and the volume required for fixed mounting is smaller than that of the rubber attachment member 31 shown in FIG. Furthermore, as compared with the M-shaped mounting member 41 shown in FIG. 4, the volume required for the fixed mounting can be reduced because there is no rim portion.
