In one aspect, a torque limiter may include a roller provided on one end of a lever member that selectively engages an engagement recess. The other end of the lever member is connected to an end of a tension spring to urge the lever member in the direction to engage the one end of the lever member in the engagement recess.

Torque limiter

Provided is a screw fastener provided with the function of a torque limiter which allows a high limit value to be set for the fastening torque without increasing the size thereof or the spring force of the spring member, and is easy to assemble and service. A multiple plate torque limiter is formed by a plurality of drive disk members () and a plurality of driven disk members () between a first member () and a second member (), and the first member () and the second member () are detachably joined to each other by a retaining screw ().

Screw fastener

Disclosed is a guide roller wherein bearings are held in a housing, and liquid mixed with abrasive grains is prevented from entering the interior of the housing through a small hole, thereby improving service life. The guide roller is configured to comprise a housing wherein the bearings are held in the housing, and the housing has a shaft hole wherein a support shaft is inserted that is installed upon the bearings. The shaft hole is formed to have a tapered wall, and the diameter of the hole decreases continuously toward the interior of the housing.
