PROBLEM TO BE SOLVED: To provide a multiaxial extruder whose disassembling and cleaning work can be quickly and simply performed. SOLUTION: In a multiaxial extruder, in a cover 11 of a shaft supporting wall body 6, there are formed a plurality of inside-bolt insertion holes 13 through which heads 8h of fixing bolts 8 can pass as a plurality of bolt insertion holes 7. In a holding portion 12 of the shaft supporting wall body 6, as the plurality of bolt insertion holes 7, there are formed a plurality of elongate outside-bolt insertion holes 14 having small-diameter portions 14s through which a shaft 8a of the fixing bolt 8 can pass and smaller than the head 8h of the fixing bolt and a large-diameter portion 14b through which the head 8h of the fixing bolt 8 can pass, and which are made to communicate with each other, with each longitudinal direction of the plurality of elongate outside-bolt insertion holes 14, and made to be in parallel with a sliding direction of the holding portion 12. With a plurality of the fixing bolts 8 loosened, the holding portion 12 is made to be freely movable along a sliding direction across a position where the fixing bolt 8 is inserted into the small-diameter portion 14s of the outside-bolt insertion hole and a position where the fixing bolt 8 is inserted into the large-diameter portion 14b.
