1. An electromagnetic valve unit configured to be held sandwiched between a receiving portion of a housing portion of control equipment and a pressing member in an axial direction of the electromagnetic valve unit, comprising:
a shoulder portion configured to be opposed to the receiving portion of the housing portion; and
an annular elastic member provided with a protruded portion configured to be inserted into a recessed portion formed at the shoulder portion,
wherein the annular elastic member is further provided with an annular deformation portion that is deformable in the axial direction of the electromagnet valve unit so as not to press the protruded portion in the axial direction,
the recessed portion is formed to be recessed in the axial direction,
the protruded portion is formed to be protruded in the axial direction,
the annular elastic member has an outer diameter side portion which does not overlap with the protruded portion in the axial direction, an inner diameter side portion which does not overlap with the protruded portion in the axial direction, and an intermediate portion which is disposed between the outer diameter side portion and the inner diameter side portion and overlaps with the protruded portion in the axial direction,
the annular deformable portion is formed by the outer diameter side portion and the inner diameter side portion,
part of the annular elastic member is protruded in the axial direction from an upper surface of the shoulder portion in a state in which the protruded portion is inserted into the recessed portion and in which the annular elastic member is not pressed, and
an outer peripheral surface and an inner peripheral surface of the protruded portion are stepless surfaces.
