Abstract:
A vibration generating device (101) comprises: a housing (HS); a movable body (MB); a guidance means (GM) that reciprocally guides the movable body (MB) along the left-right direction within the housing (HS); a magnetic flux source (5) that is attached to the movable body (MB); a coil (4) that is attached to the housing (HS); and a biasing means (BM) that generates a magnetic force that causes the movable body (MB) to move toward the center of the movable range when in a position that deviates from the center of the movable range of the moving body (MB). The guidance means (GM) includes a fixed-side end surface (FS) configured along the left-right direction in a rail (9), a movable-side end surface (MS) configured along the left-right direction in a magnetic flux source holding member (6), and a ball set (7) that is rollably sandwiched between the fixed-side end surface (FS) and the movable-side end surface (MS).
