  • the central elastic means 45 is accommodated between the lower surface of the stepped portion 35s of the central hole 35 of the body portion 30 and the upper surface of the enlarged diameter portion 41b of the core rod 41.
  • the distance between the lower surface of the stepped portion 35s of the central hole 35 of the body portion 30 and the upper surface of the enlarged diameter portion 41b of the core rod 41 is the distance between the central elastic means (compression coil spring) 45 in the non-operating state. It is configured to be shorter than the length. Therefore, at least in the non-operating state (the non-operating state of the ejection device 100 or the non-operating state of the operation button 80), the central elastic means 45 is in the compressed state.
  • the central elastic means 45 Since the central elastic means 45 is in the compressed state, stress (restoration stress) is generated in the central elastic means 45 to return to the original state or to extend the spring. Therefore, the central elastic means 45 applies an upward force to the lower surface of the stepped portion 35s of the central hole 35 of the body portion 30, while a downward force is applied to the upper surface of the enlarged diameter portion 41b of the core rod 41.
  • the core rod 41 is fixed to the operation button 80, and the core rod 41 and the operation button 80 are integrated. Therefore, the force applied to the enlarged diameter portion 41b of the core rod 41 is the operation button 80. It is also transmitted to.

In addition, the force (load) required for the user to press down the operation button 80 can be reduced. As a result, the difference between the force required for the third operation and the force required for the first operation and the second operation can be reduced, and the user can perform either operation without discomfort.
  • the normal user tends to feel a burden (load) when starting to press the operation button 80.
  • the central elastic means 45 since the central elastic means 45 generates the maximum stress in the non-operating state (FIG. 3) of the discharge device 100, the force required to start pressing the operation button 80 can be effectively reduced.
  • the central elastic means 45 In the third operation, when the user pushes down the operation button 80 to the maximum downward, the central elastic means 45 has the original length and the restoring stress is not generated even if the central elastic means 45 has the original length. It may be in a compressed state in which restoring stress is generated. However, in a configuration in which a restoring stress is generated in the central elastic means 45 at the time of maximum pressing, the action of reducing the load required for pressing the operation button 80 by the user can be sustained through the pressing operation, which is preferable.

  • the force applied upward to the operation button 80 by either one of the pump unit elastic means 25A or 25B can be made larger than the force applied downward to the operation button 80 by the central elastic means 45. Therefore, for example, the spring constant of the pump unit elastic means 25A and the spring constant of the pump unit elastic means 25B can be made larger than the spring constant of the central elastic means 45, respectively. As a result, even when the operation button 80 is pressed down with either the pressing head 60A or 60B pressed down, the operation button 80 can return to the original position when the pressing is released.
