- This embodiment has the following advantages.
- a clutch 21 is provided between the rotating shaft 13 of the motor 5 and the worm shaft 56.
- the torque generated by the rotating shaft 13 and the worm shaft 56 connected thereto via the clutch 21 is significantly smaller than the torque generated by the worm wheel 43 and the helical gear 42. Therefore, the load on the clutch 21 between the rotating shaft 13 and the worm shaft 56 is small.
- the clutch 21 does not need to have such a high strength, and the strength required for the clutch 21 can be reduced and the clutch 21 can be downsized. As a result, the drive device 1 can be reduced in size and cost.
- the rotating shaft 13 and the worm shaft 56 are connected via a clutch 21, and are originally separated at the stage of manufacturing the driving device 1. Therefore, when assembling the drive unit 1, three units which are separately controlled, namely, the motor 5 having the rotating shaft 13, the output unit 6 having the worm shaft 56, and the clutch 21 Can be easily assembled. Also, the management of these three units 5, 6, 21 becomes easy.
- the clutch 21 is mounted on the mounting cylinder 57 of the output unit 6, and the driven rotating body 25 is fitted on the worm shaft 56.
- the clutch 21 also functions as a mechanism for compensating for misalignment between the rotating shaft 13 and the worm shaft 56. Therefore, it is not necessary to separately provide a dedicated configuration for compensating for such misalignment, and the cost of the driving device 1 can be reduced.
- the misalignment between the rotating shaft 13 and the worm shaft 56 occurs because the shafts 13 and 56 are separate parts. However, by allowing the misalignment between the two shafts 13 and 56 and compensating for the misalignment with the clutch 21, it is possible to prevent the unreasonable force from being applied to the two shafts 13 and 56. it can. This enables smooth rotation of both shafts 13, 56.
- the rotating shaft 13 and the worm shaft 56 are formed by one common shaft, when the motor 5 is connected to the output unit 6, there is a possibility that bending force will be applied to the common shaft. There is. This imposes a load on the bearings that receive the force ⁇ common shaft, not only making it impossible for the common shaft to rotate smoothly. Therefore, it is necessary to adopt a complicated bearing structure. On the other hand, in the present embodiment in which the rotating shaft 13 and the worm shaft 56 are formed as separate components, such a problem does not occur.
- the mounting cylinder 57 supporting one end of the worm shaft 56 also serves as a member for fixing the clutch 21 to the output unit 6.
- the clutch 21 is mounted on the mounting cylinder 57 supporting the worm shaft 56, the clutch 21 and, more specifically, the driven rotor 25 can be easily arranged coaxially with the worm shaft 56. However, misalignment between the driven rotor 25 and the worm shaft 56 can be avoided. As a result, generation of abnormal noise and vibration due to misalignment between the driven rotor 25 and the worm shaft 56 is prevented.
- the clutch housing 22 and the mounting cylinder 57 have splines 22 d and 57 a, respectively.
- the engagement of the two splines 2 2 d and 57 a reliably prevents the rotation of the clutch housing 22 with respect to the mounting cylinder 57, that is, the unit housing 41.
- a rubber cushioning member 44 is provided between the helical gear 42 and the end plate 45. Due to the elasticity of the cushioning member 44, relative movement between the helical gear 42 and the end plate 45 is allowed. This prevents, for example, when a load is applied to the window glass 9, that load is transmitted to the components constituting the output unit 6 and the motor 5 in a shocking manner.
- each component of the worm gear mechanism An impact is prevented from being applied to the teeth of the parts 42, 43, and 56, and smooth movement of the parts is ensured.
- the roller 26 of the clutch 21 Only when force is transmitted from the lift mechanism 8 to the output unit 6, the roller 26 of the clutch 21 enters the licking state. When power is transmitted from the motor 5 to the output unit 6, the roller 26 is in a free state. If a clutch having a structure in which the roller 26 is locked even when power is transmitted from the motor 5 to the output unit 6 is adopted, the roller 26 and the roller 26 are It is easy to put a burden on the members that do. In this respect, the clutch 21 of the present embodiment, in which the roller 26 is in the lip state only when a force is transmitted from the lift mechanism 8 to the output unit 6, is excellent in durability.
