Abstract:

[Problem] To provide an oil passage switching device with improved performance in comparison with existing technology. [Solution] This oil passage switching device is equipped with: a first movement member that moves freely between a first position and a second position; a second movement member that, when the first movement member is in the first position, forms a first oil passage connected to a first through-hole and a second through-hole and is pressed by operating oil supplied from a third through-hole, thereby causing an elastic member to contract, and when the first movement member is in the second position, forms a second oil passage connected to the first through-hole and the third through-hole; and a locking member that holds the first movement member in the first position in a separated state where a first locking member and a second locking member are arranged side by side, and moves the first movement member to the second position in a housed state where either the first locking member or the second locking member is housed inside the other.
