ガイド部材。[Claims for Utility Model Registration] (1) In the recess formed on the inner surface of the outer cylinder member,
In a steel guide member fitted with an inner cylinder member having a coefficient of thermal expansion smaller than that of the outer cylinder member, at least one end face of the inner cylinder member and a step surface of the recessed part that abuts the inner cylinder member are inclined surfaces. A steel guide member characterized by: (2) One end surface of the inner cylindrical member and the stepped surface of the recessed portion that abuts the same are inclined surfaces, and the other end surface of the inner cylindrical member and the stepped surface of the recessed portion that abuts it are vertical surfaces; As described in item 1 above, the inclination angle θ of the inclined surface is as follows: θ=tan −1 d2l [where d represents the trunk diameter of the inner cylinder member and l represents the trunk length of the inner cylinder member] steel guide member. (3) Both the front and rear end surfaces of the inner cylinder member and the step surfaces of the recessed portions that contact each end surface are inclined surfaces, and the inclination angle θ of each inclined surface is θ=tan −1 dl [where d is the inner cylinder member. The steel guide member according to item 1 above, wherein the body diameter of the member and l represent the body length of the inner cylinder member.
