1. An inner-rotor-type motor comprising:
a housing including an assembly space and an assembly opening communicating with the bottom of the assembly space;
a stator being received in the assembly space;
a rotor rotatably positioned in the housing via a bearing;
a bearing seat including a socket and coupled to the assembly opening of the assembly space,
wherein a first recess with an opening formed at an end of the socket is defined by an upper wall of the socket, a second recess with another opening formed at another end of the socket is defined by the said upper wall and a circumferential side wall of the socket, and a stopper is at least a part of the upper wall of the socket and arranged between the first recess and the second recess.
2. The inner-rotor-type motor as defined in claim 1, wherein the socket has a plurality of slits arranged in the circumferential side wall of the socket and communicating with the second recess.
3. The inner-rotor-type motor as defined in claim 2, wherein the socket has a plurality of coupling portions, with each one of the coupling portions being a laterally extending groove formed at the closed end of the slits and communicating with the second recess, with an angle between extending directions of the slit and coupling portion.
4. The inner-rotor-type motor as defined in claim 1, wherein the opening of the first recess has a diameter not less than an outer diameter of the bearing.
5. The inner-rotor-type motor as defined in claim 1, wherein the socket has a first positioning portion formed on an outer periphery of the circumferential side wall of the socket and a second positioning portion formed on an inner periphery of the side wall of the socket close to the opening of the second recess.
6. The inner-rotor-type motor as defined in claim 4, wherein the socket has a first positioning portion formed on an outer periphery of the circumferential side wall of the socket and a second positioning portion formed on an inner periphery of the side wall of the socket close to the opening of the second recess.
7. The inner-rotor-type motor as defined in claim 6, wherein the first positioning portion and the second positioning portion are selected from stepped structures.
8. The inner-rotor-type motor as defined in claim 1, wherein the bearing seat includes a base coupled to the opening of the second recess.
9. The inner-rotor-type motor as defined in claim 4, wherein the bearing seat includes a base coupled to the opening of the second recess.
10. The inner-rotor-type motor as defined in claim 8, wherein the base has a shoulder and a plurality of pressing portion, with the shoulder forming an outer periphery of the base while the pressing portion flexibly formed in a center of the base.
11. The inner-rotor-type motor as defined in claim 9, wherein the base has a shoulder and a plurality of pressing portion, with the shoulder forming an outer periphery of the base while the pressing portion flexibly formed in a center of the base.
12. The inner-rotor-type motor as defined in claim 1, wherein an abutting ring leaning against an inner periphery of the first recess is made of a metal material.
13. The inner-rotor-type motor as defined in claim 1, wherein a wear-proof plate mounted in the first recess leans against a side of the stopper.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A medicine feeding device which comprises a tablet case for storing a medicine and wrapping paper wound in a roll state and wrapping paper wound in a roll state while an upper surface is opened and a lower end is folded and which wraps the medicine discharged from the tablet case in the wrapping paper, the medicine feeding device comprising:
a nozzle inserted into the continuously pulled-out wrapping paper from above to feed the medicine discharged from the tablet case into the wrapping paper,
a tip of the nozzle being provided with a tapered guide through which the medicine can be passed.
2. The medicine feeding device according to claim 1, wherein the nozzle is slidable to a far side of the upper surface.
