A control valve filter is provided, which does not require more components or require more steps in production, is less likely to be deformed or damaged when attached to a control valve, and of which engagement unit is not detached. A first engagement unit 16 and a second engagement unit 17 are formed to be engaged with each other at a divided portion formed in a substantially ring-shaped frame of a control valve filter. The first engagement unit 16 includes a first inclination surface 16a and a recessed portion 16b. The second engagement unit 17 includes a second inclination surface 17a capable of coming into close contact with the first inclination surface 17a and a proj ectionportion 17b engaged with the recessed portion 16b. The recessed portion 16b and the projection portion 17b are engaged from the diameter direction of the frame 11, and the first inclination surface 16a and the second inclination surface 17a are in close contact with each other, whereby the first engagement unit 16 and the second engagement unit 17 are engaged with each there, which is not engagement based on so-called snap-fit, and therefore, the recessed portion and the projection portion can be prevented from being deformed or damaged, and the shape thereof is simple, so that the trouble in production can be saved. |
