Title:
ROTARY MOTION/LINEAR MOTION CONVERTING MOTOR
Document Type and Number:
Japanese Patent JPH10215545
Kind Code:
A
Abstract:

To provide a rotary motion/linear motion converting motor which facilitates the phase adjustment by a method, wherein the function of a stopper pin is given to the rotation restricting part of a motor shaft, instead of using the stopper pin.

In a rotary motion/linear motion converting motor, which has a rotor 32 whose rotation direction can be reversed, and a motor shaft 33 which is guided by sliding in a bush 41 and screwed into the rotor 32 to convert the rotary motion of the rotor 32 into a linear motion, the motor shaft 33 consists of a screw part 33a screwed into the rotor and a rotation restricting part 33b fitted to the bush 41. The rotation restricting part 33b has a contact part 33c, which is brought into contact with a stopper part 32b, which is formed on the end part of the rotor. With this constitution, the number of positions related to precision is reduced from three to two, so that the precision can be improved.
