体１３には、その中心部位に従動軸１６を連結す
るための連結孔１７が設けられている。 Inside the worm gear 10, there is an elastic disc body 11 formed in an annular shape from an elastic material such as rubber;
semi-circular metal shells 12a and 12b that cover almost the entire outer circumferential surface and are firmly adhered to the circumferential surface;
A cap-shaped metal bearing body 13 firmly adhered to the inner circumferential surface of the disc body is strongly fitted, and the elastic disc body 11 is inserted through the gap provided at opposite ends of the semi-annular shell bodies 12a and 12b. Recessed portion 1 cut out toward
4 is fitted with a protrusion 15 that projects integrally with the inner circumferential surface of the gear 10. The cap-shaped bearing body 13 is provided with a connecting hole 17 at its center for connecting the driven shaft 16.

性盤体１１によつて緩衝される。 In the torque buffer device configured as described above, the assembly consisting of the shell bodies 12a, 12b, the elastic disk body 11, and the bearing body 13 fitted inside the worm gear 10 protrudes from the inner surface of the gear 10. The worm gear 10 is operatively connected to the worm gear 10 by fitting the protrusion 15 therein with the recess 14 on the assembly side, so that the rotational torque of the worm gear 10 is transmitted to the driven shaft 16 via the assembly. Sudden torque when starting and stopping the electric motor is buffered by the elastic disc body 11 of the assembly.
とくに、トルクを緩衝するための弾性盤体１１

り、確実なトルク伝達が得られる。 In particular, an elastic disc body 11 for buffering torque.
In the case where the metal shells 12a and 12b are integrally connected to the outer periphery of the disk, there is a function to prevent the elastic disk from being deformed in the radial direction during torque transmission, and reliable torque transmission can be obtained.
また、前記のように、ウオーム歯車内に嵌着さ

を防止できる。 Further, as described above, the assembly fitted into the worm gear is composed of the shell bodies 12a, 12b and the elastic disc body 1.
1 and a bearing body 13,
The resilient force of the elastic disc body 11 allows the assembly to be firmly fitted and held on the inner circumferential surface of the gear, thereby preventing the assembly from moving in the thrust direction when transmitting rotational torque of the gear.
さらにまた、前記構成によれば、トルクを緩衝

車の内側に収容されているので、第１図および第
２図に示した従来のトルク緩衝装置の巾寸法Ｗを
大巾に縮少することができる。 Furthermore, according to the above structure, since the assembly including the elastic disc body 11 for buffering torque is housed inside the annular worm gear, the conventional torque buffer device shown in FIGS. The width dimension W can be greatly reduced.
前記殻体１２ａ，１２ｂを開環形に分割したの

つて、この殻体の分割数は、前述した弾性盤体の
ラジアル方向の変形状態を考慮して任意に定め得
るものである。 The reason why the shells 12a and 12b are divided into open ring shapes is to firmly fit the assembly to the inner peripheral surface of the worm gear by the elastic force of the elastic disk 11. The number of divisions can be arbitrarily determined in consideration of the radial deformation state of the elastic disc body described above.
さらにまた、弾性盤体１１を環形でない完全な
円盤形となし、その中心側面に従動軸の連結用軸
受体を固定して構成することもできる。 Furthermore, the elastic disc body 11 may be formed into a complete disc shape instead of an annular shape, and the bearing body for connecting the driven shaft may be fixed to the central side of the elastic disc body 11.

型に構成できるトルク緩衝装置が得られる。 As described above, according to this invention, the gear that is operatively connected to the electric motor side is formed into an annular gear, and inside the gear is a circular elastic disc made of an elastic material such as rubber. An assembly consisting of an open ring-shaped metal shell fixed to the outer peripheral surface of the gear, and a bearing body fixed to the axial center of the elastic disc body is fitted, and the assembly is provided on the inner peripheral surface of the gear. Since the protrusions are fitted into the recesses formed on the circumferential surface of the elastic disc body, a reliable buffering function is exerted against sudden torques when starting and stopping the electric motor, and this also prevents damage to the buffer member. To obtain a torque buffer device that can be safely used for a long period of time without any fear, is easy to manufacture and assemble, and can be constructed in a small size.
