PROBLEM TO BE SOLVED: To provide a slide core guide part having good workability in attaching an angular pin to a pin holder and higher accuracy.SOLUTION: In a slide core guide part 9, magnets 4 are fixed to side surfaces 211A and 211B of a pin holder 2 to be attached with an angular pin 10, and a slide plate 3 holding trunnion parts 22 of the side surfaces 211A and 211B of the pin holder 2 in a rotatable way is composed of a ferromagnetic material attracted by the magnet 4. Because at least one of the pin holder 2 and the magnet 4 is pressed toward the slide plate 3 by the magnetic force of the magnet 4, there is produced, without the need of fine protrusions formed on the outer peripheral surface 222 of the trunnion parts 22, such a friction resistance as to be capable of preventing rotation of the pin holder 2 relative to the slide plate 3 due to the self-weight of the pin holder 2 but allow smooth manual rotation of the pin holder 2, between the surface 31B of the slide plate 3 and a movable surface in contact with the surface 31B of the slide plate 3, with the movable surface being at least one of the side surfaces 211A and 211B of the pin holder 2 and the adsorption surface 41 of the magnet 4. |
