Document Type and Number:
Japanese Patent JP6706510
Kind Code:
B2
Abstract:
The present application discloses a drive device for deriving a driven gear situated on a movable portion of a power generator device which generates electric power according to a change in a flow direction of fluid. The drive device includes a drive gear configured to mesh with the driven gear; and a drive portion including a rotary shaft portion inserted into a through-hole, which is formed in the drive gear. The drive gear includes an inner wall surface which forms a contour of the through-hole. The rotary shaft portion comes into contact with and is pressed against the inner wall surface on a first imaginary plane orthogonal to a rotational axis of the rotary shaft portion, and on a second imaginary plane away from the first imaginary plane in an extending direction of the rotational axis.
