A pin 30 is fitted into any one of the through holes 29 of the shaft support portion 27, and the helical gear 3 is rotatably supported by the base portion 23.
[0009]
The helical gear 3 is formed integrally with the helical gear portion 36 and the helical gear portion 36, in which teeth 35 are formed on the outer peripheral portion, and are rotatably supported by the shaft support portion 27 of the main body 2. And an arm portion 37 protruding outward from one end surface 21 of the hollow portion 22 of the main body 2. The pin 30 is inserted into the center hole of the helical gear portion 36, and the helical gear portion 36 is rotatably supported by the shaft support portion 27 of the main body 2.
[0010]
One end 41 side of the worm shaft 4 is disposed in the cylindrical portion 28, and the other end 42 side protrudes from the cylindrical portion 28 and is rotatably supported by the cylindrical portion 28. The worm shaft 4 is integrally formed with a worm screw portion 43 having a worm screw formed on the outer periphery and one end of the worm screw portion 43, and is rotatably fitted in a recess 44 formed in the main body 2. One end 41, a connecting portion 45 formed integrally with the other end of the worm screw portion 43, and a serration 53 are formed on the outer peripheral surface. And the other end 42 projecting therefrom. A collar 46 is fitted to the open end of the cylindrical portion 28.
[0011]
The handle 5 is provided with a recess 52 at one end 51 for receiving and fixing the other end 42 side of the worm shaft 4 protruding from the cylindrical portion 28, and the recess 52 has the other end of the worm shaft 4. A serration 54 that fits into the serration 53 formed in 42 is formed. By mutual fitting of the serrations 53 and 54, the rotation of the handle 5 is transmitted to the worm shaft 4 without being idle. It has become.
[0012]
A handle grip 6 having a substantially elliptical cross section is attached to the distal end 61 of the handle 5 via a connecting pin 62 so that the handle 5 is rotated by gripping the handle grip 6.
[0013]
The main body cover 7 as a decorative cover is fitted and attached to the base 23 and the mounting portions 25 and 26 so as to cover the base 23 and the mounting portions 25 and 26.
