Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

Abstract: In a linear motion guide unit, in order to prevent direct collision of a roller, or a rolling element, with an end portion of a carriage, an extending portion of a spacer of an end cap is disposed at the end portion of the carriage for absorbing impact resulting from collision of the roller. The spacer has the extending portion which protrudes from the spacer at a position adjacent to an inner circumferential surface of a turnaround passage and which has a wall surface continuous from the inner circumferential surface of the turnaround passage. The wall surface of the extending portion serves as a collision receiving surface for receiving a colliding roller. The carriage has a housing recess which is formed at an end of a raceway groove thereof and to which the extending portion is fitted.

Abstract: A linear motion guide unit prevents damage to a corner portion of an end surface of a carriage resulting from high-speed rolling of the rolling elements, and eliminates the need for strict dimensional management of facing end surfaces of the carriage and a spacer. A crowning is formed at an end portion of the carriage, and an R chamfered portion is formed at a corner of an end surface of the carriage. An R chamfered portion is formed at a corner of the end surface of the spacer. The R chamfered portions define a valley portion between the facing surfaces of the carriage and the spacer. The rolling elements roll above the valley portion while striding it to thereby be prevented from colliding against the corner portion of the end surface of the carriage, whereby damage to the corner portion of the end surface of the carriage can be prevented.
