Abstract

An apparatus for inhibiting undesirable movement of a bicycle electrical component comprises a motor (206) having an output shaft (206a) that rotates around a rotational axis, a driving member (207) disposed on the output shaft, and a driven mvember (208) that is driven by the driving member. A movement control unit (209) controls movement of the output shaft in a direction other than rotation around the rotational axis (R).

Description

technical field [0001] The present invention relates to a driving device, in particular to an electric driving device for a bicycle that electrically drives an operating mechanism that can be mounted on a bicycle. Background technique [0002] Recently, various electric drive devices employing electric motors are also used in the field of bicycles. For example, electric drive devices such as electric transmissions for electrically shifting bicycles and auxiliary drives for assisting driving force of bicycles are widely used (for example, refer to Patent Document 1). A conventional electric drive device is a device that drives a front derailleur (an example of an operating mechanism) of a bicycle via a shift cable, and has: a housing member that can be mounted on the bicycle; A motor positioning unit (an example of an electric drive device) for positioning a shift cable; and a shift control unit housed in the housing member side by side with the positioning unit and controll...
