PROBLEM TO BE SOLVED: To provide a hot air heater capable of preventing coming-off of a unit without using a screw.SOLUTION: At an operation part mounting metal fitting 19 fixed in a hot air heater body 1, a hole 26 for an insertion claw and a hole 27 for a hook claw are formed in which an insertion claw 15 and a hook claw 18 of a receiving part unit 12 are inserted, and one end of an operation unit 6 comes close to the insertion claw 15 which is located above the hole 26 for an insertion claw and fitted in the hole 26 for an insertion claw. Therefore, when some load is applied to the insertion claw 15 so as to press and bend it, the insertion claw 15 comes into contact with a tip of a fixing part 11 of the operation unit 6; thereby, a wedge-like portion of the insertion claw 15 does not come off from the hole 26 for an insertion claw, and the insertion claw 15 can be prevented from coming off. |
