To provide a knitting machine enabling overall noise level to be reduced especially in a region where an operator is present.

This knitting machine 1 has a frame, a knitting tool and a work region 2, if necessary, has a knitted fabric-winding apparatus. The work region can be approached from the operation side. At least one transparent and soundproof glass 10 is installed so as to be able to move along the region 2 from a first position located at the operation side 11 to a second position enabling an operator to approach the region 2. Thus, noise level in a main region where an operator is present is lowered.
