【考案の詳細な説明】 本考案はモータの回転駆動に依り振動部に設けた偏心重
りを回転せしめてなる回転振動型の按摩器に於ける上記
偏心重りを含む振動部の構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a vibrating part including the eccentric weight in a rotary vibration type massaging device in which an eccentric weight provided on the vibrating part is rotated by the rotational drive of a motor.

従来、この種の偏心重りを有する回転振動型の按摩器は
振動部に於ける偏心重りの回転は振動子として必要不可
欠のものであるが、同時に過度な回転ムラをガタ付きな
く軸支するために回転軸を高精度に仕上げた軸受にて枢
支する外、偏心重りの両端に１枚ないし数枚のスペーサ
やワッシャー等を介挿し、上記両軸受間に完全に支承す
る様構成している。Conventionally, in rotary vibration massagers with this type of eccentric weight, the rotation of the eccentric weight in the vibrating part is essential as a vibrator, but at the same time, it is necessary to axially support excessive rotational unevenness without rattling. In addition to the rotating shaft being supported by a highly precisely finished bearing, one or several spacers, washers, etc. are inserted at both ends of the eccentric weight, so that it is completely supported between the two bearings. .

従ってこれを組立てる場合には軸受を−・体的に設けた
取付枠に対し、一方の軸受から回動軸を挿入すると共に
固定された軸受間に於いて、先づ一端のスペーサ並びに
ワッシャーを回動軸に環合し、次に偏心重りを環合し、
更に他端のスペーサ並びにワッシャーを環合しなから回
動軸を挿通し、他方の軸受に貫通しなければならない。Therefore, when assembling this, first insert the rotation shaft from one bearing into the mounting frame provided physically, and then rotate the spacer and washer at one end between the fixed bearings. Connect to the moving shaft, then connect the eccentric weight,
Furthermore, the spacer and washer at the other end must be fitted together, and then the rotating shaft must be inserted and penetrated into the other bearing.

このため、組立作業者は予め偏心重りと両軸受間の隙間
を小さく構成されたその僅かな間隙にスペーサ等の小部
材を介挿しなければならない結果と成る外、偏心重りは
通常その偏心効果を大にする為に縁部が肉圧に構成され
ていることから組立作業が極めて困難であり、作業能率
が著しく低下する等重大な問題を有していた。For this reason, the assembly worker has to insert small parts such as spacers into the small gap between the eccentric weight and both bearings, which is configured to be small in advance. In order to increase the size, the edges are made with flesh pressure, which makes assembly work extremely difficult and poses serious problems such as a significant drop in work efficiency.
