{Idle pulley} (Mach.), a pulley that rests upon a belt to tighten it; a pulley that only guides a belt and is not used to transmit power.

{Idle wheel} (Mach.), a gear wheel placed between two others, to transfer motion from one to the other without changing the direction of revolution.

{In idle}, in vain. [Obs.] ``God saith, thou shalt not take the name of thy Lord God in idle.'' --Chaucer.

Syn: Unoccupied; unemployed; vacant; inactive; indolent; sluggish; slothful; useless; ineffectual; futile; frivolous; vain; trifling; unprofitable; unimportant.

Usage: {Idle}, {Indolent}, {Lazy}. A propensity to inaction is expressed by each of these words; they differ in the cause and degree of this characteristic. Indolent denotes an habitual love to ease, a settled dislike of movement or effort; idle is opposed to {busy}, and denotes a dislike of continuous exertion. Lazy is a stronger and more contemptuous term than indolent. [1913 Webster]
