Abstract
A faucet includes a main body, a control valve, a drive shaft, and a handle. The drive member of the drive shaft has a peripheral wall contacting with the mounting recess of the control seat of the control valve and formed with a plurality of spacing portions to reduce a contacting area between the drive member and the mounting recess to prevent the drive member from being expanded excessively due to absorbing the water to jam the mounting recess, so that the drive shaft is operated easily and conveniently, thereby facilitating the user operating the faucet.
