PROBLEM TO BE SOLVED: To provide an inexpensive and compact crusher of resin bumpers for vehicles in which various kinds of parts are less damaged by the crushing impact, the noise level is low, and the maintenance man hour is reduced. SOLUTION: Any wear of driving system parts can be reduced, and the noise level can be reduced by absorbing the crushing impact by transmitting the driving force of a reduction gear motor 6 to two shafts facing each other and fixed to a blade via a chain 9. The cost of the blade and the maintenance man hour can be considerably reduced, and the noise level can also be reduced by providing an attachable/detachable blade which presses and cuts the bumper in the transverse direction between a tip edge of the blade and a columnar part of the shafts, and shears the bumper in the longitudinal direction between side surfaces facing each other of the blade. Smooth crushing can be performed by successively removing bumper tips caught between the blades by a scraper. |
