Abstract
Provided is a feed mechanism that has a small number of parts and that is suitable for downsizing. A feed mechanism (1) includes: a base (2); a movable body (3); a feed screw (4) configured to move the movable body (3) relative to the base (2); and a torque generation member (15) formed with a female thread (15b) that is threadedly engaged with the feed screw (4). The movable body (3) is formed with a housing hole (12) extending in a direction orthogonal to the feed screw (4), and the torque generation member (15) is housed in the housing hole (12).
Claims16
A feed mechanism comprising:
- a base;
- a movable body;
- a feed screw configured to move the movable body relative to the base;
- and
- a torque generation member formed with a female thread that is threadedly engaged with the feed screw, wherein
- one of the movable body and the base is formed with a housing hole extending in a direction orthogonal to the feed screw, and the torque generation member is housed in the housing hole.
A method for manufacturing a feed mechanism including a base;
- a movable body;
- a feed screw configured to move the movable body relative to the base;
- and a torque generation member formed with a female thread that is threadedly engaged with the feed screw, the method comprising:
- inserting the torque generation member into a housing hole in one of the movable body and the base, the housing hole extending in a direction orthogonal to the feed screw;
- and
- generating the female thread on an inner surface of a through-hole of the torque generation member by use of the feed screw.
