    摘要： Provided is a slide component that can prevent deposit formation on a sealing face as well as promoting circulation of a fluid on sealing faces while fulfilling both conflicting conditions of sealing and lubrication, to maintain the sealing function of the sealing faces for a long period of time. The slide component includes a pair of slide parts that relatively slide on each other, one of the slide parts being provided in a sealing face with fluid circulation grooves 10 that communicate with a high-pressure fluid side via inlet portions and outlet portions and are separated from a low-pressure fluid side by land portions, the other of the slide parts being circumferentially provided in a sealing face with a plurality of interference grooves 15, 16, 17, 20 for producing pressure variations in a fluid in the fluid circulation grooves 10, adjacent ones of the interference grooves 15, 16, 17, 20 being set to have different shapes.

    摘要： Provided is a slide component that can prevent deposit formation on a sealing face as well as promoting circulation of a fluid on sealing faces while fulfilling both conflicting conditions of sealing and lubrication, to maintain the sealing function of the sealing faces for a long period of time. One slide part 5 is provided, on a low-pressure side of a sealing face thereof, with a negative pressure generation mechanism 10 including a negative pressure generation groove 10. The negative pressure generation groove 10a communicates with a high-pressure fluid side and is separated from a low-pressure fluid side by a land portion R. The other slide part 1 is provided, in a sealing face thereof, with at least one interference groove 15 communicating with the high-pressure fluid side for producing pressure variations in a fluid in the negative pressure generation groove 10a. The at least one interference groove 15 has an end 15a on an inside-diameter side extending to a position to radially overlap the negative pressure generation groove 10a.
