PURPOSE:To make the bearing structures of direct-boss-type and intersecting- type pointer shafts common in a rotary-magnet type vehicle-speed display apparatus. CONSTITUTION:A rotor 4, which is turned by the action of the magnetic field generated with a rotary magnet 1, is provided so as to face the rotary magnet l, which is rotated in response to the rotation of a wheel, through a gap. In this rotary-magnet type vehicle-speed display apparatus, the indication is performed with a pointer provided on a pointer shaft 5, which is turned with the rotor 4. In this apparatus, a lower bearing 9 for supporting the pointer shaft 5 is formed so that a hole for the bearing is provided in ax iron plate. The bearing 9 is fixed to a body so as to support one-end side of the pointer shaft 5 at the upper part of the rotor 4 so that the rotor 4 is rotated freely. The other side of the pointer shaft 5 is rotatably supported with a bearing, which is constituted of a bracket 6, a washer 8, a recess part 71 of an upper body 7, a through hole and a bearing member 15. At the same time, the movement of the pointer 5 in the axial direction is regulated. |
