PROBLEM TO BE SOLVED: To provide easy assemblability by performing assembly work while confirming a proper assembly state of an elastic member in a linear vibration motor in which a movable element formed from a magnet and a weight and the elastic member are assembled into a frame body.SOLUTION: A linear vibration motor 1 includes: a movable element 10 including a magnet 11 and a weight 12; a frame body 2 which supports the movable element 10 in a freely slidable state in an uniaxial direction; a coil 4 which is fixed to the frame body 2 and drives the magnet 11 in the uniaxial direction; and an elastic member 6 for applying an elastic force that is repulsive to a drive force applied to the magnet 11, to the movable element 10. The frame body 2 includes a bottom face plate 20 including a bottom face part 20A to which the coil 4 is fixed; a top face plate 21 including a top face part 21A that is opposite to the bottom face part 20A; and a front face plate 22 which supports the elastic member 6 oppositely to the uniaxial direction. The bottom face plate 20 includes a partial side surface part 20B which is deflected from a side edge of the bottom face part 20A and with which an open part 20C is formed in a central portion in the uniaxial direction.SELECTED DRAWING: Figure 1 |
