といつた不都合を有している。 The wheel that forms part of the winding/needle rotating mechanism is
Normally, its position is normally regulated by engaging a bolt that is slidably attached to the square shaft of the winding stem and is displaced depending on the pulled-out position of the winding stem.
Because the wheel is cylindrical, it is difficult to hold it in the correct position when the winding stem is pulled out or attached to the winding stem, and sometimes it may fall off. It has some inconveniences when stored away.

いる。 1 and 2 show an embodiment of the present invention, in which reference numeral 1 denotes a helical wheel slidably attached to the square shaft portion 2a of the winding stem 2; , each has an annular tooth 1 that meshes with a small iron wheel (not shown).
b, and teeth 1c that engage directly or indirectly with the number wheel or the date wheel, and the center is provided with a neck portion 1a that engages with a later-described wheel support member 3 and a bolt (not shown). There is. Reference numeral 3 denotes a wheel support member which is a characteristic part of the present invention. This member 3 made of an elastic material such as resin supports the wheel wheel 1 as shown in FIG. 1 with the top plate 4 removed. A holding part 31 that enters into the above-mentioned neck part 1a and holds this part, and left and right leg pieces 32, 32 bent from both ends at right angles to the axial direction of the winding stem 2 form a U-shape in plan. The two convex portions 34, 34 formed on the leg pieces 32, 32 are brought into sliding contact with the inner edges of the recesses 5a on the base plate 5, which are recessed on both sides of the winding stem 2 in parallel therewith. Therefore, it is possible to move integrally with the wheel 1, and at the same time, it is attached so that it does not slip out upward by the upper base plate 4 that protrudes above the recess 5a. Note that reference numerals 33 and 33 in the figure are two clamping pieces formed upright on the holding part 31 so as to frictionally lock the neck part 1a of the handwheel 1; A back presser supporting the support member 3 is shown.

そのまま巻真軸位置に保持される。 In the embodiment described above, when the winding stem 2 is moved to the needle turning position, mainspring winding position, calendar correction position, etc., the wheel 1 moves over the square shaft 2a of the winding stem 2 via a bolt (not shown) to the small iron wheel. , it moves to a position where it meshes with the Kichi wheel or the Date wheel, etc.
Along with this, the handwheel support member 3 engaged with the neck portion 1a is also stabilized by sliding the two front and rear convex portions 34, 34 provided on the left and right leg pieces 32, 32 onto the inner edge of the concave portion 5a of the base plate 5. Since the hand wheel 1 moves while maintaining the correct posture and meshes with the small iron wheel, etc. without causing the wheel wheel 1 to swing, the needle wheel 1 can be moved without any oscillation motion, and the needle turning operation etc. can be performed without any trouble. Furthermore, when the winding stem 2 is pulled out for repair or the like, the support member 3 that is in sliding contact with the inner edge of the recess 5a of the base plate 5 is locked to that part by friction.
At the same time, the overhanging portion of the upper base plate 4 prevents it from coming off upward, so the wheel 1 frictionally held by the holding pieces 33 is held at the winding stem position without falling off.

ができる。 In the embodiment shown in FIG. 3, the thickness of the support member 3 is made approximately equal to the width of the neck portion 1a of the wheel 1,
According to this embodiment, frictional engagement with the wheel wheel 1 is possible without providing the clamping part 33.
The support member 3 can be easily punched and formed from a plate material.

できる。 Moreover, the holding portion 31 is formed to match the neck portion 1a of the wheel 1, and the left and right leg pieces 32, 3
2 are provided with two convex portions 34, 34 on each side, and are brought into sliding contact with the inner edge of the concave portion of the main plate 5, and also with the surface of the back presser foot 6, so that the shaft center is always maintained without causing any swinging. The wheel 1 can be moved so that it is aligned with the winding stem axis, and the mesh wheel 1 and the small iron car etc. can be properly engaged, and when the winding stem 2 is installed, the axis of both can be moved. By matching the numbers, fitting to the wheel 1 can be performed accurately and smoothly.
