Claims

[Scope of utility model registration request]

(1) A drive shaft with a spiral groove formed on the outer periphery, a driven wheel with a recess formed on the outer periphery with the same pitch as the spiral groove pitch of the drive shaft, and a recess between the spiral groove of the drive shaft and the driven wheel'. In a worm type transmission device having a large number of rolling members interposed between the drive shaft and the driven wheel to transmit the rotation of the drive shaft to the driven wheels, and a rolling member falling-off prevention member covering the rolling members, the rolling member falling-off prevention member is A worm type transmission device characterized in that it is formed to surround a driving wheel, and one rolling member is disposed in each recess of the driven wheel.

(2) The worm type transmission device according to claim 1, wherein the recessed portion of the driven wheel is formed in a substantially hemispherical shape and the rolling member is made of a spherical body.

(3) Utility model registration claim 1 or 2, characterized in that the recessed portion of the driven wheel is formed as a linear groove with a predetermined lead angle with respect to the rotational axis of the driven wheel, and the transmission member is made of a cylindrical body. The worm type transmission device described in Section 1.

(4) The worm type transmission device according to any one of claims 1 to 3 of the utility model registration claim, characterized in that the outer circumferential surface of the drive shaft is formed in the shape of a medium-low drum.
