Title:
ROTATION/LINEAR MOTION CONVERSION MECHANISM AND BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2020085097
Kind Code:
A
Abstract:
To provide a rotation/linear motion conversion mechanism of a novel structure with less inconvenience such as preventing a fastening state of a male screw and female screw from occurring, and a brake device.SOLUTION: A rotation/linear motion conversion mechanism comprises: a first rotary member that rotates around a central axis; a second rotary member that is rotatable relative to the first rotary member, has one screw of a male screw and a female screw meshing with each other, and is rotatable around the central axis in conjunction with the first rotary member; a linear motion member that has the other screw of the male screw and the female screw, and linearly moves according to the rotation of the second rotary member; and a torque limiter that has a first transmission surface provided on the first rotary member, and a second transmission surface provided on the second rotary member and contacting the first transmission surface, and is configured such that the first transmission surface and the second transmission surface slide when the transmission torque between the first transmission surface and the second transmission surface is equal to or greater than a predetermined value.SELECTED DRAWING: Figure 3
