If you use the bolt with the bearing as the fulcrum when moving the gear turning device, there is no need to loosen it because the bolt can rotate between the bearing and the case, and you can move the gear turning device by simply loosening the other fixing bolts. The large gear and small gear can be engaged and disengaged by rotational movement.
以下第１〜４図を参照し本考案の一実施例につ

る。 The gear turning device 1 is fixed to a flywheel housing 8 with bolts 5 and 6. A large gear is cut on the outer periphery of the flywheel 2.
The pinion 7 is supported by the case 3 of the gear turning device, and consists of the pinion, a spanner hook part 7a, and a coaxial part 7b. Further, as shown in FIGS. 3 and 4, the gear turning device 1 can be assembled by simply removing the bolt 6 without loosening the bolt 5 due to the sliding action between the case 3 and the bolt 5 of the gear turning device 1. Bearing 4 that can rotate and move the
is provided. The relationship between the length t b of this bearing 4 and the thickness t of the mounting portion of the case 3 is t b >t.
次に前記実施例の作用について説明する。 Next, the operation of the above embodiment will be explained.

せ、ボルト６を固定すれば作業準備完了となる。 When the gear turning device 1 is used to turn the crankshaft, the large gear of the flywheel 2 and the small gear 7 are engaged, and when the gear turning device 1 is not used, the large gear of the flywheel 2 and the small gear 7 are engaged. In order to disengage the small gears 7, each bolt 6 is removed, the gear turning device 1 is rotated about the bolt 5, and the bolt 6 is fixed, and the preparation for work is completed.

Since the present invention is configured as described above, in order to rotate the gear turning device to disengage and disengage the large gear and small gear of the flywheel, the bolts that support the rotation are connected between the bearing 4 and the case 3. Since the gap rotates by sliding action, there is no need to loosen it, and the gear turning device can be moved by simply replacing the bolts other than the fulcrum, which has the advantage of simplifying the operation.
