Pressurizing device

A pressurizing device comprising:

• a syringe internally including a storage portion configured to store a fluid;
• a plunger configured to move in a first direction with respect to the syringe, and discharging the fluid stored in the storage portion to outside of the syringe when the plunger moves to one side in the first direction;
• a body connected to the syringe and internally including a through hole through which the plunger is inserted;
• a regulating member configured to move in a second direction intersecting the first direction, between a separated position of being separated from the plunger and a contact position of being in contact with the plunger;
• a lever configured to rotate about a rotation axis to move the regulating member from the contact position to the separated position in accordance with a rotation operation;
• and
• a rotation mechanism including the rotation axis and provided at a position overlapping with the regulating member in the second direction, supporting the lever to be rotatable with respect to the regulating member, configured to move in the second direction in accordance with rotation of the lever, and configured to move, when moving to one side in the second direction, the regulating member from the contact position to the separated position by applying a force to the regulating member, wherein
• the body includes
• a first hole portion communicated with the through hole, and
• a second hole portion extending along the first direction from a side surface of the first hole portion,
• the regulating member is supported by the body and is configured to move between the contact position of being in contact with the plunger inserted through the through hole and the separated position by moving along the first hole portion,
• the pressurizing device further includes
• a lever body including the lever, a protruding portion provided at one end of the lever and housed in the second hole portion, and a part of the rotation mechanism positioned between the lever and the protruding portion,
• when the lever rotates, the protruding portion moves in the first direction along the second hole portion and the rotation mechanism does not move in the first direction, and
• wherein the lever serves as a point of force application, the protruding portion serves as a point of support, and the part of the rotation mechanism serves as a point of action.
