An inner peripheral surface of a tube-shaped inner casing has a regular hexagonal shape when viewed from the axial direction, a plurality of pins are arranged in the inner casing so as to take a posture parallel to the axial direction of the inner casing, and in this arrangement, a plurality of rows of the pins arranged in a predetermined direction are arranged in a direction perpendicular to the row direction of the pins, the adjacent pins of the adjacent rows are offset from each other in the row direction of the pins, and each pin contacts the pins adjacent thereto.

Marking head and marking device

A rim mounting device configured in such a manner that, even if a permanent magnet breaks due to impact produced during mounting thereof by magnetic attraction, the rim mounting device can be handled easily after the breakage of the permanent magnet. The rim mounting device is provided to a tire testing device having a spindle for rotating a tire and is adapted that a rim is mounted to the tip of the spindle. The rim mounting device is provided with: a rim mounting section provided to the tip of the spindle, having a rim mounting surface capable of making contact with the rim, and having mounting recesses formed in the rim mounting surface so as to be arranged side by side; permanent magnets inserted in the mounting recesses, respectively, and generating magnetic force for attracting the rim to the rim mounting surface; and scatter suppressing members. The scatter suppressing members are provided in the mounting recesses, respectively, and when the permanent magnet inserted in each mounting recess breaks, suppress scatter of fragments of the permanent magnet.

A spindle direction engaging device moves at least one of spindles in a mutually separating direction to closely engage a lock piece or a lock portion in a spindle direction of spindles while the lock piece is locked to the lock portion when a tire is not mounted. A second spindle includes a groove extending in a peripheral direction along an outer periphery thereof in sliding contact with the lock piece; sliding surfaces of the lock piece and the groove are receiving portions formed as flat surfaces to receive separating forces acting on both the spindles. A correction device corrects a gap between an inner ring of the spindle bearing and rolling elements of the spindle bearing, or a gap between an outer ring of the spindle bearing and the rolling elements of the spindle bearing, while the spindle is rotating. Preload bolts include a coolant passage formed by hollowing a corresponding portion passing a mounting hole of a detector, and a coolant can thus be supplied to the coolant passage.
