There is provided a condition detection apparatus for detecting a present operating condition of a linear rolling motion guide apparatus, and the condition detection apparatus includes an AE sensorfor detecting a waveform elastically generated at least due to rolling of balls included in the linear rolling motion guide apparatus and mutual collision of the balls and generating an electric detection signal corresponding the detected waveform, a waveform shaping unit, an A/D converter, and a signal processing unitjudging a content of the operation condition in response to the generated detected signal Sae.

Condition-detecting device, method, and program, and information-recording medium

A rolling element interference preventer for a guide device prevents a number of rolling elements rolling at regular intervals in a continuous circulation path of the guide device from interfering with each other. The rolling element interference preventer is formed of a thermoplastic resin elastomer having a physical property in accordance with an expression, (A&#xd7;B)&#xf7;C&#x2267;18, where A represents a 10% elongation stress, B represents a tensile strength, and C represents a bending modulus of elasticity.
