PROBLEM TO BE SOLVED: To secure a transmission route at the time when vibration of a movement is transmitted from a rear cover to an arm and contrive lightweight of the rear cover and facilitation of manufacture by providing a vibration transmission means so that the bottom face of the rear cover is brought into contact with the arm by uniform material. SOLUTION: A movement 2 rotating an eccentric weight and providing a motor generating vibration is engaged with the inside diameter of a case 3. The movement 2 is fixed by pressing and deforming a fixing projection 2a composed of an elastic member provided on the movement 2 by a rear cover 4 incorporated in the case 3. A recess part 3 provided on the case 3 and a projection part 4b provided on the rear cover 4 are engaged with each other and the rear cover 4 is integrated with the case 3. A means for transmitting vibration is provided on the rear cover 4, i.e., the projection part 4a is provided at the opposite side of the movement 2. The projection part 4a is constituted of curvature shape so as to be adhered on the shape of an arm. It is effective by providing the direction of the projection part 4a in the directions from 12 o'clock to 6 o'clock. |
