Electromagnetic valve and flow path device

An electromagnetic valve that includes a movable portion that is movable along a central axis extending in an axial direction and that switches a state between an opened state in which a first flow path portion and a second flow path portion located on one side of the first flow path portion in the axial direction are connected to each other via a first hole and a closed state in which the first hole is blocked and the first flow path portion and the second flow path portion are disconnected, the electromagnetic valve comprising:

• a main body that has a solenoid that causes the movable portion to move in the axial direction and a cover that accommodates the solenoid;
• a tube member with a tubular shape that extends from the main body to the other side in the axial direction;
• and
• a connection flow path portion that connects an outer portion of the electromagnetic valve to an inner portion of the tube member,
• wherein the movable portion has
• a shaft portion that projects on the other side in the axial direction from the main body and is inserted into the inner portion of the tube member,
• a valve body that is provided at the shaft portion and blocks the first hole from the one side in the axial direction in the closed state, and
• a partitioning portion that widens outwardly in a radial direction from an outer peripheral surface of a portion of the shaft portion that is inserted to the inner portion of the tube member,
• the partitioning portion is located on the one side in the axial direction beyond the valve body and partitions the inner portion of the tube member into a first accommodation portion and a second accommodation portion that is located on the other side of the first accommodation portion in the axial direction,
• the second flow path portion is connected to the second accommodation portion in the opened state,
• the connection flow path portion is provided at the movable portion and connects the first flow path portion to the first accommodation portion in the closed state, and
• the first accommodation portion accommodates a fluid flowing through the first flow path portion and is disconnected from the second flow path portion in the closed state.
