Operation apparatus
 An operator is prevented from slipping out when it is pulled, and an operating apparatus equipped with such an operator can be realized at lower production cost. A hole is formed in the operator. A member to be operated is formed with a pawl such that when the operator is pushed down onto the member, the pawl is engaged with the hole. The operator is thereby firmly coupled with the member. Under this arrangement, if the operator is pulled, the member is also moved integrally with the operator. Moreover, the operating apparatus further includes a case comprising a hole. Thus, the pawl is further prevented from slipping out of the hole because any outward bending of the pawl caused by the pulling is restricted due to a peripheral part of the hole of the case.
