The present invention provides a switching device characterized in that: a protruding part 10 slides on a first guide section 61 and a third guide section 63 using an urging force from a pressing body 41 greater than an urging force from an elastic member 31; the protruding part 10 slides on a second guide section 62 and a fourth guide section 64 using the urging force from the elastic member 31; the protruding part 10 at a first stop position 10a moves, in order, a first guide section start position 61a, a first guide section end position 61b, a second guide section start position 62a, and a second guide section end position 62b and arrives at a second stop position 10b; and the protruding part 10 at the second stop position 10b moves, in order, a third guide section start position 63a, a third guide section end position 63, a fourth guide section start position 64a, and a fourth guide section end position 64b and arrives at the first stop position 10a. The switching device can constantly use a portion of the urging forces in the axial direction, for movements in the circumferential direction, and carry out smooth switching operations without applying an excessive load to members.
