摘要： Provided is a measuring device 1 for measuring the size of an object comprising a body 2, and a spindle 3 which is screwed into the body 2 and axially advances and retracts by screwing with respect to the body 2, the measurement being based on the axial displacement of the spindle 3 effected by the revolution of the spindle, wherein the spindle is screwed into the body 2 via a multiple-start thread 31. Therefore, it is possible to displace the spindle 3 at a high speed, which improves the operability of the measuring device.

摘要： A stator (42) is hooked in a frame body (10) away with a prespecified space from a spindle (2), so that it is not necessary to fix the stator with a screw. The stator (42), therefore, can easily be mounted, and further as it is not necessary to provide a screw hole in the frame body (10), so that the need for waterproofing processing associated with a screw hole is eliminated. Further the stator (42) is hooked in a protrusion (53) of an electronic unit (50) inside the frame body (10) away with a prespecified space from the spindle (2), so that a rotation thereof in the peripheral direction of the spindle due to play and rattle is small and a measurement error can be suppressed.

摘要： A compact and simple linear actuator includes a spindle to a main body so as to be capable of moving in an axial direction, displacement detection device, a motor, and a transmission mechanism. The displacement detection device detects a movement displacement amount of the spindle. The motor is disposed adjacent a proximal end one of the spindle and on the same axis as the spindle. The transmission mechanism transmits turning force of the motor to the spindle. The transmission mechanism includes a first rotary member fitted to the proximal end of the spindle and integrally rotating with the spindle, a second rotary member fitted to a rotor of the motor, and connection rods for transmitting rotation of the second rotary member to the first rotary member. The connection rods have axes that are parallel to an axis of the spindle while being displaced from the spindle axis. The connection rods are rigidly connected to one of the first and second rotary members, and slidably received by the other of the first and second rotary members.

摘要： A rotary movement converting mechanism for converting a rotary movement of a rotary body (43) into a linear movement of a movable body (2) has a support body (42) fixed to a body frame (3) and provided with a slit (42A) along an axial direction of the rotary body (43), a spiral groove (43A) formed on the inner circumference of the rotary body (43), and a top member (41) provided on the movable body (2). The top member (41) has an engaging member (41 A) inserted through the slit (42A) and having a tip end engaged with the spiral groove (43A), and a stop member (41C) for stopping the linear movement of the movable body (2) when a load is applied on the linear movement of the movable body (2). Accordingly, when a load is applied on the linear movement of the movable body (2), the linear movement is stopped and the minute displacement of the movable body (2) is restrained, thereby enhancing the stability of a measuring instrument in measuring a workpiece.
