Claims

[Scope of utility model registration request]

A main rod is provided on a fixing unit of a spacecraft so as to be movable in the direction of attaching and detaching equipment to the fixing unit, and has an engaging part formed at its tip with a fitting member on the equipment side, and urges the main rod forward. an elastic member that closes and opens in conjunction with the retraction and advancement of the main rod by pressing and retracting the fitting member against the engagement portion, and holding the fitting member;
a pair of restraint arms that release the lock pin; a lock pin that can be inserted into and removed from a lock hole formed in the main rod when the main rod is in the retracted position; and an elastic force that biases the lock pin in a direction to fit the lock pin into the lock hole. A spacecraft onboard equipment attachment/detachment mechanism comprising: a member; and a fluid pressure cylinder for releasing the fitted state between the lock pin and the lock hole against the biasing force of an elastic member against the lock pin.
