To provide a crusher capable of restraining generation of clogging by restraining the deposition of fine grain fractions on a screen member of a vibrating feeder.

The crusher, crushing an object to be crushed, includes a jaw crusher 30, a conveyor 40 which conveys objects crushed by the jaw crusher 30 to the outside, and a vibration feeder 20 which screens objects to be crushed for each grain size and feeds the screened objects to the jaw crusher 30. The vibration feeder 20 includes a main screen member 25 which screens and conveys objects to be crushed larger than a crushing target grain size set to be crushed by the jaw crusher 30 and removes fine grain fractions lower than the crushing target grain size, and an auxiliary screen member 24 which is mounted to cover the top of the main screen member 25 and screens and conveys objects to be crushed larger than consolidation inducement grain size set to be larger than the crushing target grain size. The object to be crushed is fed to the jaw crusher 30 through two paths: a feed path through the main screen member 25 and a feed path through the auxiliary screen member 24.
