目前,有一種馬達裝置,如圖4所示,其包括馬達主體110X和齒輪120X,其中,馬達主體110X具有收納轉子、定子和齒輪組(此處,轉子、定子和齒輪組均未圖示)的外殼111X以及從該外殼111X突出的輸出軸112X,齒輪120X與輸出軸112X的從外殼111X突出的部分卡合,並利用與齒輪120X的端面抵接的C形環150X防止齒輪120X從輸出軸112X脫落。At present, there is a motor device, as shown in FIG. 4, which includes a motor body 110X and a gear 120X, wherein the motor body 110X has a rotor, a stator, and a gear set (here, the rotor, the stator, and the gear set are not shown) The housing 111X and the output shaft 112X protruding from the housing 111X, the gear 120X is engaged with the part of the output shaft 112X protruding from the housing 111X, and the C-ring 150X which is in contact with the end face of the gear 120X is prevented from the gear 120X from the output shaft 112X came off.
在上述馬達裝置工作時,通過驅動馬達主體110X內部的轉子相對於定子旋轉,轉子的旋轉可通過齒輪組傳遞至輸出軸112X,從而帶動齒輪120X旋轉。During the operation of the above motor device, by driving the rotor inside the motor body 110X to rotate relative to the stator, the rotation of the rotor can be transmitted to the output shaft 112X through the gear set, thereby driving the gear 120X to rotate.
上述馬達裝置可應用於投影儀,例如,如圖5所示,在投影儀的外殼210X中安裝上述馬達裝置(通常是將馬達主體110X固定於外殼210X),以使齒輪120X的中心軸L1與透鏡鏡筒220X的外周上設有的鏡筒側齒輪221X的中心軸L2相互平行地隔開適當間隔,並使齒輪120X與鏡筒側齒輪221X嚙合,藉此,馬達裝置通過驅動齒輪120X旋轉使透鏡鏡筒220X旋轉,就能進行投影儀的對焦等。The above motor device can be applied to a projector.

Specifically, a hole portion 202A extending through the gear 20A is provided in a radial center portion of the gear 20A, and an output shaft 12A protruding from the housing 11A of the motor body 10A passes through the hole portion 202A of the gear 20A (here, for example, a hole The portion 202A is formed in a D shape or the like when viewed in the axial direction of the output shaft 12A, and the portion of the output shaft 12A that is engaged with the hole portion 202A is formed into a corresponding shape to realize the rotation prevention of the gear 20A relative to the output shaft 12A.
