イロ用スピンモータ。A substantially cylindrical hollow housing 2 fixed coaxially with the axis of the cymbal ring 1; a stator 3 fixed to the outside of the housing; and a hollow housing surrounding the housing and the stator with gaps left on the top and side surfaces. In a gyro spin motor having a cylindrical rotor 4; a cap 8 is tightly fitted to the lower end of the housing to form an oil reservoir, and the rotor 4 is fixed to the center of the upper surface of the cylinder and is vertically mounted. It has a rotating shaft 11 extending to near the bottom of the oil reservoir below, and the rotating shaft is rotatably supported around the center line of the housing by an upper ball bearing 5 and a lower ball bearing 6 on the inner wall of the housing. It has a central passage 14 extending substantially the entire length of the axis, which opens into the oil sump at its lower end, and at its upper end a diametric through passage formed near the upper end of the rotating shaft and above the upper ball bearing. 14' and the side opening 12.
A lamp wick 15 is filled in a T-shaped passage consisting of a central passage 14 and a through passage 14'.
- A gyro spin motor with a built-in lubricating oil circulation mechanism.
