Claims

[Claims for Utility Model Registration] 1. A roller outer ring constituting a rotating roller, a rolling bearing fitted inside the outer ring, a shaft supporting the rotating roller via the rolling bearing, and an end portion of the rotating roller support shaft. a holding member for a rotating roller support shaft having a thrust receiving part that is fitted and in contact with the roller outer ring; the rotating roller supporting shaft is a straight shaft without a step, and the thrust receiving part has lubricating properties; 1. A rotating roller device, characterized in that the holding member is made of a material with good thermal conductivity. 2 A needle bearing is used as a rolling bearing, a roller outer ring is fitted and fixed to the outer ring of the needle bearing, and a part of the side surface of the holding member of the rotating roller support shaft is brought into contact with the side surface of the roller outer ring via a lubricating layer to perform thrusting. The rotating roller device according to claim 1, which is formed to support a load. 3 A shell type needle bearing is used as the rolling bearing, and a thrust support piece made of a lubricating material is installed between both sides of the roller outer ring and the end face of the rotating roller support shaft on the holding member side. Claim 1: The structure is such that it is interposed separately from the member.
The rotating roller device described in . 4. Any one of claims 1 to 3, wherein the holding member of the rotating roller support shaft is a holding piece made of a material with good thermal conductivity that can be fitted into a mounting recess provided in the rotating roller mounting part. The rotating roller device described in . 5. The rotating roller device according to any one of claims 1 to 3, wherein the holding member for the rotating roller support shaft is provided directly on the mounting body of the rotating roller that constitutes the rotating roller mounting section.
